Coastal walk from Port Isaac to Tintagel

The walk ends at Tintagel Visitors' Centre (and associated car parks), so you'll need to begin or end with a road journey from Tintagel to Port Isaac.

  1. Walk down the hill from Port Isaac towards Port Gaverne to reach the old pilchard sheds at the bottom of the hill.

    There were 4 large pilchard cellars built in Port Gaverne at the start of the 1800s which can still be seen at the bottom of the hill leading up to Port Isaac. In their heyday, in the early 1800s, it is suggested that they could have processed 1,000 tons of pilchards in a week.

  2. Follow the road behind the beach to the small car park on the far side of the beach.

    Industrialisation of fishing and the introduction of rail transportation during Victorian times led to over-exploitation of the Cornish pilchard stocks to meet an insatiable demand from the Italian market and the population crashed. Possibly as a knock-on consequence of the lack of availability, demand from Italy dried up and this has allowed pilchard stocks to recover.

  3. Follow the road uphill for a short distance until you reach a flight of steps to the left.

    Port Gaverne, the tiny settlement and inlet neighbouring Port Isaac, was more prominent than Port Isaac in the past. In fact, the settlement at Port Gaverne dates back to mediaeval times, being recorded in the 1300s. The sheltered inlet made it a good place to launch boats and it is still a popular place to launch small craft today.

    The name was previously recorded as Port Kerne and on maps from the 1800s as Port Keverne. One of the quirks of the Cornish language is that "k" often transforms into "g" when placed after another word, which might have resulted in "Porthgeverne" (which is not far from how some of the locals still pronounce it).

  4. Climb the steps and follow the path to a junction. Keep left at the junction on the well-worn path out towards the headland, passing a pair of benches, until you reach a final path leading off to the right, just before the path ahead crosses a raised concrete area with an iron railing.

    During the summer, particularly at weekends, Port Gaverne is a popular spot for Pilot Gig racing.

    The six-oared elm boats known as Pilot Gigs were general-purpose work boats, but one of their uses was to transport the pilot to and from a ship, which resulted in the name. The first boat to meet a ship gained the business of transporting the captain (and thus being paid) and thus a "race" came into being, with different boats competing for business. Today, Gig Racing is of a recreational nature, but the boats are still built to the exact well-documented specification of the originals. Elm wood is highly resistant to water, so much so, that town water mains were made of elm before the widespread availability of iron.

  5. Turn right and follow the path along the edge of the coast until another small path leads off to the left just before the path ends on a wider path.

    Look out for Fulmars which nest along the cliff faces. You'll often see them soaring over the tops of the cliffs as they circle in to land.

    The fulmar is a grey and white bird related to an Albatross although it can be mistaken at a distance for a gull. Close up, the beak is the giveaway: the fulmar has a tube on its beak which is visible as a black bar across the beak at a distance. The tube is a gland for excreting salt from the seawater that they drink. As a defence mechanism, the fulmar regurgitates foul smelling oil from its stomach - the name comes from the Old Norse for "foul" (full) and "gull" (mar). The oil disrupts the waterproofing of predatory birds' feathers in a similar way to a crude-oil spill, so they avoid preying on fulmars.

  6. Take the inner of the two paths on the left to stay back from the cliff edge, then follow the path past a number of benches until it eventually emerges on the road.

    All along the North Cornish coast, the use of shell-rich sand to fertilise the acidic soils was a major part of the local economy until the end of the 19th Century. At Port Gaverne in Victorian times, the local women and children could earn as much as their seafaring men-folk by digging the sand at low tides and placing it above high water for the farmers to collect.

  7. Turn left onto the road and after the wall, turn left onto the drive of Silver Spray (with a Coast Path sign to Trebarwith Strand) and follow it to the end of the tarmac.

    The road from Port Gaverne which joins the Delabole road was quarried out in the early 1800s by the Delabole Slate company and known as "The Great Slate Road". Around 100 ships a year came to Port Gaverne to collect slate, each capable of carrying 50-80 tonnes. It would take thirty wagons, pulled by over a hundred horses, to load a sixty ton ship. The slates were loaded by women, who then packed them in straw to protect them on the voyage. The incoming ships also brought coal from Wales and limestone, for the local limekiln, which was used to whitewash the cottages.

  8. Follow the grassy path from the end of the tarmac past the end of the fence. Continue on the coast path ahead along the cliff top to cross a stile. Then continue to where the path forks.

    Gug is a North Cornish dialect word for a coastal inlet or cave. It is related to the mining terminology vug for a rock cavity. Both derive from the Cornish word for cave now standardised as gogow but previous forms included vogga. The word for a man-made underground chamber found in prehistoric settlements - fogou - also derives from this.

  9. Keep right at the fork (on the more well-worn path) and continue on the coast path until it drops into a valley and you reach a wooden walkway.

    Gurnards used to be extremely common in Port Isaac Bay - it was almost impossible not to catch one if you were dangling some bait on the sandy seabed in the 1980s. There are still some around but since they were "rediscovered" by the catering industry, their numbers have declined noticeably.

    Gurnards are a family of spiny fish that live on the sea bed. The rays of their pectoral fins have evolved into something approximating fingers which they use to feel their way along the sea bed and find any worms or shrimps. Plymouth aquarium have some gurnards as they are quite entertaining to watch trundling along.

    Gurnards have quite a large head and thin body. The relatively small amount of edible flesh and small bones meant they were not popular to eat, and consequently it was one of the most widely discarded fish from trawlers seeking more lucrative bottom-dwelling species.

    Gurnard has been rediscovered recently as a culinary fish as the flavour and texture of the flesh are both nice and has been championed by a number of celebrity chefs. It is quite a fast-growing fish which bodes well for a sustainable fishery.

  10. From the walkway, follow the path up to the top of the cliff to reach the corner of a fence at the top.

    Ocean sunfish can sometimes be seen on hot summer days basking on the surface, with their fin flapping out of the water as they lie on their side sunbathing. They are extremely weird-looking fish, resembling a large round dinner plate with no real tail, just two large fins at the top and bottom and two smaller ones on the sides (doing the flapping). The average weight of a full grown adult sunfish is a tonne - the largest known bony fish, which is particularly impressive on a diet principally of jellyfish.

    Jackdaws can be distinguished from other members of the crow family by their short black beaks and grey necks. They are smaller than all the other black birds in the crow family and are only slightly larger than jays.

  11. Follow the path along the fence. Continue on this for a mile, crossing some stiles along the way, until you descend to a stream at the bottom of a steep valley.

    Because bluebells spread very slowly, they're considered to be an indicator of ancient woodland sites. In areas where trees are not very old, the fact there are bluebells around can indicate that there has been a wood on a site for a very long time. Even if there are no trees there at all, bluebells tell us that there was woodland there some time in the past. The bluebells along the coast are a relic of the gnarled oak woodland that used to grow here before it was cleared for grazing. There is still a patch of the ancient oak woodland left along the coast at Dizzard.

    The common name "foxglove" dates back many hundreds of years but the origin is unknown. The "gloves" almost certainly refers to the shape of the flowers, and the Latin name Digitalis (finger-like) is along similar lines. The curious part is the "fox" and many different suggestions have been made as to where it came from. It is possible that it is a corruption of another word. One suggestion is "folks" which was once used to mean "fairies".

    There are more than 20 breeding pairs of peregrine falcons along the coast from Bude to Padstow.

    The peregrine falcon can reach over 322 km/h (200 mph) during its hunting stoop (high speed dive) making it the fastest member of the animal kingdom. In 2005, a peregrine was measured at a top speed of 389 km/h (242 mph). The air pressure at this speed could damage a bird's lungs. However small bony tubercles on a falcon's nostrils guide the powerful airflow away, enabling the bird to breathe more easily while diving. In Cornish dialect, these falcons are known as "winnards" and local expressions include "shrammed as a winnard" (meaning chilled) and "rumped up like a winnard" (meaning huddled).

  12. From the bottom of the valley follow the path to where it forks.
  13. At the fork, you can take either path as they rejoin and neither has steps. The one to the right is further away from the cliff edge but is bare earth so can be slippery after rain. The cliff edge path is more stony. Continue on the path up the headland to a stile at the top.

    As you walk along the coast path, you'll likely see a number of gulls gliding along the cliff edges. The large ones, with black feathers all along their back and a red mark on their bill, are Greater Black-backed Gulls.

    The Greater Black-backed Gull is the largest member of the gull family and a bird of formidable size, with a wingspan of nearly 6ft. Unlike other gulls, the Greater Black-backed Gull is highly predatory. Young birds are a significant portion of its diet and it tends to live amongst other seabirds where it can eat the neighbours. It has also been known to swallow whole rabbits and even eat young lambs. It often steals food from other seabirds using its large size to intimidate them into dropping it, and consequently it is sometimes referred to as a pirate.

  14. Cross the stile and follow the path over 2 more stiles and past a waymark to where a path joins from the right with a granite post to the left.

    The beach at the bottom of the cliffs is Barrett's Zawn.

    Barrett's Zawn is a remote beach on the rugged coast between Port Isaac and Tintagel. It is located just north-west of the farm hamlets of Hendra. The beach can only be accessed by sea or via the now disused tunnel on the north side of Delabole Point which was known locally as the "Donkey Hole", because it was once used by donkeys bringing up slate from the beach quarry below.

    It is still just possible to crawl through the tunnel to the beach but part of the tunnel roof has collapsed and it is now not recommended to go through the tunnel as the high cliffs above are unstable. If you do decide to risk it, be aware: there is one narrow squeeze in the tunnel where you'll need to get down onto your belly to slide over a rock, though the rest of the tunnel is reasonably tall; you will also need a torch as it's pitch black in the central section of the tunnel.

  15. At the waymark, keep left on the coast path and follow it to a waymark in a quarried area at the bottom of the valley.
  16. From the waymark, follow the coast path down to the bottom of the valley to a stile and cross the river over the stepping stones. Follow the path up the other side until you reach a stile over a fence.

    The names of many coastal features are derived from words in the Cornish language:

    • Pen - Headland (Cornish for "top" or "head")
    • Pol - often used to mean Harbour (literally "Pool")
    • Porth - Port but often used to mean Cove
    • Zawn - sea inlet (from the Cornish "sawan" meaning chasm)

    Note that Haven has Saxon origins (hæfen in Old English) which is why it tends to occur more in North East Cornwall (Millook, Crackington, Bude etc).

  17. Cross the stile (or go through the gate if open) and follow the path over a second stile until you reach a third stile at the edge of a valley.

    Basking sharks are the second largest fish in the world with adults typically reaching 20-25ft in length and the shark with the smallest brain relative to its body size. They slowly cruise along, usually in small groups, filtering plankton. They migrate in search of plankton blooms and are seen off Cornwall between May and October. Occasionally they come in close to the shore on sandy beaches, causing much excitement for swimmers.

    Tides in the Atlantic are closely aligned with the moon's position above the Earth which takes just under 25 hours on average to return to the same position; this is slightly more than 24, as the Earth has to chase the moon's orbit. The tides therefore shift forward by at just under an hour each day so that over a 7 day week, low tide and high tide have approximately changed places (e.g. no beach in the afternoon vs a huge beach in the afternoon).

  18. Cross the stile and follow the path down into the valley to reach a footbridge across the stream.

    Hanging valleys are common on the North Cornish coast and are created due to erosion of the relatively hard cliffs by the Atlantic waves being faster than erosion of the valley by a small river. In many cases, this results in a waterfall where the small river meets the sea cliff, though many of these are little more than a trickle in dry weather. When there is a strong onshore gale, the waterfalls sometimes run backwards!

  19. Cross the bridge and go through the kissing gate. Follow the path to a gate in the fence at the top of the valley.

    The sea carrot is technically the same species as a wild carrot, from which the carrot was domesticated, but is shorter, stouter and more splayed-out than a wild carrot. The two converge the further north and east that you go in Britain: West Cornwall is therefore the pinnacle of sea carrot evolution.

    In Cornwall, cliffs erode at an average rate of between roughly 3cm - 30cm per year depending on the hardness of the rocks and location. In reality this often happens in infrequent sudden collapses rather than as a steady, gradual process. It was found that one massive storm in 2014 caused around 100 times the average amount of erosion. There are obvious implications from climate change leading to more frequent or more intense storms.

  20. Go through the gate and continue along the coast path until you reach a waymark signposted to Tregardock beside a kissing gate.

    Next to the beach below the ruined hamlet of Dannonchapel, you can still see remains of a slate dressing and shaping floor located on a rock jutting out to sea below the main line of the cliffs. Here, lengths of wall enclose a level platform on the rock where there are traces of dressing waste. At the point nearest the mainland are rows of stacked finished slates, apparently never retrieved and now inaccessible. When the quarry was working, this rocky platform was probably linked to the mainland either by an aerial cableway (known as a blondin) or a horse-powered winch (known as a whim).

  21. At the waymark, continue on the coast path, in the direction signposted to Tregardock, until you reach a gate.

    The ruined hamlet of Dannonchapel, near Tregardock, is over 1000 years old and included a manor house first recorded in the Domesday Survey of 1086 when it was known as Duuenant. Its Domesday entry notes that it had "land for 3 ploughs" and 40 acres of pasture. The name comes from the Cornish downans which means "deep valley". The suffix "chapel" was added later in the 1300s.

  22. Go through the gate and follow the steps down into the valley to a waymark post. Continue on the zig-zag down the valley to reach a gate and footbridge at the bottom.

    In the past, when the cliffs were grazed regularly, this provided habitat for wild thyme and red ants on which the large blue butterfly depends. As farming became more intensified and cliff-top grazing stopped, the cliffs became overgrown and there was too much shade. Consequently the large blue became extinct in the UK in 1979.

  23. Go through the gate and cross the bridge over the stream then follow the path up the point. Continue through a gate near the top of the cliff until you reach a waymark beside a gate.

    In 2000, a pilot project was run at Dannonchapel for the re-introduction of the large blue butterfly in Cornwall. 12 adults and 300 larvae were released into the valley. The colony survived for seven generations before finally dying out. This showed that all the ingredients (wild thyme and red ants) are present to support all stages of the butterfly's lifecycle. A much larger population could recover from setbacks such as predation or bad weather.

  24. At the waymark, keep left on the coast path across a wooden footbridge. Follow the path alongside the fence to reach a pedestrian gate.

    In late June and July, lady's bedstraw produces clusters of tiny pale yellow scented flowers. The plant has long, thin stems with a star of very narrow leaves at intervals along the stems, a bit like rosemary, or its relative, goosegrass, but is softer than either.

    The name has arisen from its use to stuff mattresses as the scent was pleasant and also repels fleas. In Scandinavia, the plant was used as a sedative during childbirth. The plant was also used to produce red and yellow dyes. The light orange colour of Double Gloucester cheese originates from this. The flowers were used in place of renin to coagulate milk but no records remain for the method of how to do this.

    The mussel-covered rocks in the bay provide food for plaice.

    Plaice are one of the easiest flatfish to recognise by their orange spots. Young plaice eat mostly shrimps and then progress onto bigger prey such as bristle worms and mussels. Plaice are one of the quickest flatfish to be able to change their colour to blend in with their surroundings. They can complete this in as little as 10-15 min.

    Plaice can live for 40 years but due to heavy fishing, few now make it past the age of 6. It takes around 3 years before they can breed so they are at risk of overfishing. In 2006, three out of four fish stocks, including the Celtic Sea, were regarded as over-exploited by the World Wildlife Fund and in 2010, Greenpeace added plaice to their seafood red list. High discard rates of dead immature fish from trawling are particularly of concern although larger mesh sizes can help to reduce this. New fishing technology is also becoming available using water pressure or electrical pulses to raise fish from the bottom (rather than dragging heavy "tickler" chains across the seabed) which can reduce the environmental damage from trawling.

    .
  25. Go through the gate and continue on the coast path alongside several more fields until you eventually reach a kissing gate.

    Thrift is a tough evergreen plant which grows on sea cliffs and consequently it's the county flower of the Scilly Isles. To survive in this environment it needs to be able to withstand drought and salt-laden winds. Its long, thin leaves and hairy flower stems have evolved to minimise water loss.

    The Common Toadflax is recognisable from its pale yellow flowers which appear from June all the way through to October. The flowers are said to be shaped liked toads and are completely closed, only opening when a bee forces its way in to reach the nectar. Only larger species of bee, with long enough tongues, are able to reach to the bottom of the flower. In early summer the plant is regarded as resembling a flax plant, hence the name.

    Along the coast, from June onwards but particularly in the late summer and autumn, parasol mushrooms are common. They are one of the easier mushrooms to recognise due to their huge size (and umbrella shape when fully open). The brown flecks on their otherwise white flesh are caused by the rapidly expanding young mushroom bursting through a brown outer coating as it grows (a bit like "sugar puffs" breakfast cereal!). Other characteristic features include a snakeskin-like brown pattern on the stem and there's often a ring around the stem which is detached (can be carefully slid upwards to verify).

    Parasol mushrooms have firm white flesh and delicate flavour which is not strongly "mushroomy". This makes them an excellent carrier for other flavours within a sauce, adding texture and body to a dish.

    Cornwall has the longest stretch of coastline of any county in the UK, stretching for roughly 400 miles around 80% of the county, and there are over 300 beaches. Wherever you are in Cornwall, you are never more than 16 miles from the sea, and from the majority of hills you can see it on a clear day.

  26. Go through the gate and follow the path through another kissing gate and down to a waymark at the bottom of the valley.

    Tregardock beach is about a mile along the coast from Trebarwith Strand, in the direction of Port Isaac and is reached via a public footpath that crosses the coast path to reach the farm at Tregardock. There is no beach at high tide at Tregardock. As the tide goes out, several small beaches merge into a long stretch of sand. A waterfall plummets from the cliffs at the back of the beach and there are some caves within the cliffs. The largest part of the beach is on the left and this gets cut off as the tide rises, so check the tide times carefully and don't get stranded when the tide comes in!

  27. From the waymark, you can walk down to the beach, explore, and then return to the waymark to resume the walk.

    The walk continues on the coast path towards Trebarwith Strand.

    Follow the coast path over a slate footbridge and up the side of the valley to a gate.

    Common gorse flowers have a coconut-like scent but rather than fresh coconut, it is reminiscent of desiccated coconut or the popular brand of surf wax, Mr Zoggs. However, not everyone experiences the smell in the same way: for some people it's very strong and for others it quite weak. One complicating factor is that Western Gorse flowers don't have any scent, so you need to be sniffing a tall gorse plant to test yourself.

    Bluebells are also known by folk names based on their shape including Lady’s Nightcap and Witches’ Thimbles.

    Other common names for the bluebell include "wild hyacinth" and "wood hyacinth" as they are related to the hyacinth family. Their Genus name Hyacinthoides also means "hyacinth-like".

    Skylarks are the most common member of the lark family in Britain and are often known simply as "larks".

    Skylarks are one of the most widely distributed of all British birds, found from coastal dunes to mountain tops. In Cornwall, they can be seen both in coastal fields and on Bodmin Moor. The coastal heath is a particularly good habitat for them, being mild but with fairly short vegetation in which they can hunt for insects.

  28. Go through the gate and follow the coast path across Treligga Common to reach a wooden gate with a kissing gate alongside.

    Between Tregardock and Backways Cove lie the remains of Treligga Aerodrome (HMS Vulture II). Both the observation/control tower and the reinforced hut near the sea (towards Backways Cove) are still standing, as are the accommodation and service huts near Treligga village. The control tower has quite recently been repaired and converted into accommodation.

    Before the Second World War, HMS Vulture II was used as a glider site. However the Admiralty requisitioned 260 acres of land in late 1939 for the purposes of constructing an aerial bombing and gunnery range. Unusually, the entire operation at HMS Vulture II was staffed by the Women's Royal Naval Service.

    On 16 September 1943, an American B-17 Flying Fortress was forced to make an emergency landing at HMS Vulture II. The pilot, Capt Jack Omohundro, had ignored a red flare warning him to keep clear. The plane was chronically short of fuel and running on three engines after a raid on U-boat pens at Nantes in France. The bomber had left its formation to try and preserve what little fuel it had left. Spotting the tiny Treligga airstrip, he skilfully landed "wheels-down" just 50 yards short of the Wrens quarters.

  29. Go through the kissing gate and continue on the coast path until you reach a slate bridge at the bottom of the deep valley at Backways Cove.

    The carpets of tiny blue flowers on the coast during April and May are the appropriately-named spring squill, which up close is a star-shaped pale blue flower with a dark blue stamen. They achieve their early flowering by storing energy over the winter in a bulb so they can be the first flowers out on the cliffs before they become overshadowed by larger plants. They thrive in locations which are beaten with wind and salt-laden spray which they are able to tolerate but other plants, which might otherwise out-compete them, cannot.

    Gull Rock lies approximately 500 metres offshore from Trebarwith Strand and has given its name to RR Gordon's crime thriller set in the area. It is made of a very hard volcanic material that has withstood the sea whilst the slate around it has been worn away. On the seaward side, where a chunk of the rock has cracked off, the tightly folded volcanic rocks within can be seen.

    Recently the rock has turned green during the spring and summer due to rock samphire colonising the side facing the beach which is sheltered from the westerly winds, helped by fertiliser provided by the seabirds also colonising the sheltered side of the rock.

    In the 1800s, the rock at Trebarwith (or "Trebarrow" as it was known then), was known as Otterham Rock, or Rocks, acknowledging the rocks to the side of the main rock which protrude a small amount from the water. Below the surface of the water, these are part of an extensive reef.

  30. Cross the bridge and bear left to cross a wooden footbridge over a stream.

    From here you can follow the paths to the left to explore the rocky beach of Backways Cove. The path to the left, before you cross the slate bridge, leads down to the cove but is slippery in wet weather. On the other side of the footbridge, paths lead to the remains of the quarry workings.

    The shore of Backways Cove is covered in boulders from the slate quarrying that took place along the cliffs and the cove itself has been enlarged from its original natural shape by the quarrying. The cove is surrounded by high cliffs and the only access is a path cut into the rocks along side the stream. The stream percolates through the boulders on the beach and there's quite a bit of slippery weed on some of the boulders. Beyond this is a reef that stretches all the way to Gull Rock and rock platforms either side almost meet to make the cove a lagoon, leaving just a narrow opening. In winter, storm waves breaking over the reef create sea foam which is driven into the cove by the westerly winds where it collects, trapped against the high cliffs and caught in wind vortices created by the cliffs. The high cliffs also mean the cove is often in shade, particularly in the morning and in winter.

    Possibly as a result of this and its bleak rocky shore, Backways Cove features in "The International Directory of Haunted Places":

    "Backways Cove, a North Cornwall inlet just up the coast from Trebarwith Strand, is still haunted by many unidentified presences who are thought to be the spirits of shipwrecked sailors whose bodies washed up there after they drowned. Numerous ships were torn apart on the jagged rocks offshore, and the shadowy spirits of their crew are still trying to make it to shore."

    It's theoretically possible that wreckage from a vessel grounded on the reef around Gull Rock might be trapped against Dennis Point and wash ashore at Backways Cove but historical accounts of this actually happening are thin on the ground.

  31. After exploring Backways Cove (via the path leading towards the sea), return to the footbridge and then go up the steps to follow the path a short distance to where it forks. Keep left at the fork to follow the path up the headland to reach a hairpin bend in the main path with a smaller path continuing to the left.

    A tale of Backways Cove was recounted by a folklore enthusiast called Kath:

    Many years ago a man with two sons farmed in the vicinity, and on his death left his entire estate to his eldest son, cutting out the younger one without a penny. The younger son went away wracked with jealousy that fomented over time to be an obsession until, convinced that he had been cheated of his birthright he set out to wreak revenge on his elder brother. One night he crept onto the farm and set fire to the buildings. The blaze took hold and the entire property was razed to the ground. The ruins of this once prosperous farm may still be seen near Backways - a few stones from the farmhouse and outbuildings were all that remained. Only in the morning did he discover that his brother had died the day before - and left the entire estate to him.
  32. Turn right to stay on the major (upper) path and follow it to where the well-worn path bends sharply to the left.

    There are two very similar looking members of the daisy family that are both known as "chamomile". English chamomile (also known as Roman chamomile) has hairy stems and is the one used for chamomile tea. German chamomile has smooth stems and higher levels of essential oils so this one is used for chamomile-scented pharmaceuticals (shampoos etc). Pineapple weed is related and is sometimes known as "false chamomile" or more confusingly as "wild chamomile" (even though it isn't chamomile and normal chamomile is also wild!).

    English chamomile was once common in Britain but it has declined (due to land clearance and changes to farming practices) to now being classified as Vulnerable. The Southwest is now one if its last strongholds.

    The small ridges in steeply-sloping fields are known as terracettes and are caused by soil creep and their formation is accelerated by animals using them as tracks.

    When the soil gets wet, it expands and particles are lifted up at right angles to the slope. When the soil dries out, it contracts, but the particles fall vertically under gravity, landing a millimetre further downhill from where they started. Over a long period of time, the soil gradually creeps downhill.

  33. Turn left to stay on the well-worn path and follow this to a waymark beside the fence near the top of the headland.

    Heathers and heaths are members of the Ericaceae family. The formal definition of a heather is a member of the Calluna genus within this family whereas heaths are members of the Erica genus. Bell heather is actually an Erica and therefore technically not a heather but a heath.

    During stormy weather, sea foam is driven into Backways Cove by the wind and vortices form against the sheer cliffs resulting in small tornadoes of sea foam.

    Sea foam (also known as "spume") is formed due to organic compounds known as surfactants present in seawater. Under turbulent conditions, the surfactants form persistent bubbles which float to the surface, stick to each other through surface tension and are driven onshore by the wind. The surfactant compounds themselves arise from processes such as the offshore breakdown of algal blooms.

    On beaches, sea foam can conceal deep pools and gullies with an apparently flat, uniform surface. Tread carefully, especially on beaches you don't know well, to avoid walking off the edge of a precipice or vanishing into icy cold water.

  34. At the waymark, stop to admire the view and get your breath back, then follow the coast path to a gate.

    Looking back across Port Isaac Bay, the headland on the far side is The Rumps. The island off the end is Newland. The Mouls (also known as Puffin Island) is less clear as it's directly in front of the headland from this angle.

  35. Go through the kissing gate next to the gate, and bear left on the path towards the rock outcrop. Then bear right to follow the path around the headland and along the fence until you reach a corner in the fence.

    The extra distance covered by going up and down also adds to the distance shown on a map. However, despite your legs telling you otherwise, this is actually not that huge either. There are two parts to it:

    On an exceptionally arduous walk solely on the coast with lots of deep valleys, the distance travelled "up and down" is likely to be at most about 10% compared to the distance on the flat. For a more normal coastal circular walk the "up and down" distance is typically not much more than 5% of the distance on a flat map.

    The second consideration was worked out by Pythagoras. The shallower the incline, the less significant the elevation adds to the overall route distance. Even with an average gradient of 1 in 3 (which is insanely steep), you're looking at only around 10% of the total elevation distance being adding onto the route length.

    So since the elevation distance itself is already a small percentage of the route length (5-10%), the small "pythagoras" percentage (less than 10%) of the already small elevation percentage is not much more than a gnat's whisker.

  36. Keep left along the fence until you reach a flight of steps.

    In the spring, it's possible to use the wildflowers as a compass. On the Backways Cove side of the point, spring squill and thrift grow on the south-facing slope facing the sun. The north side facing Trebarwith Strand gets much less sun so shade-loving plants such as bluebells and red campion grow here.

  37. Descend 170 steps to a reach a level area of path.

    There are spectacular views of Trebarwith Strand and Penhallic Point on the way down. Make sure you stop walking to admire the view (or read this!) and look where your feet are going when descending the steep steps.

  38. Continue on the path to descend a flight of 33 steps, then follow the path to a waymark just before a stile.

    The headland on the far side of the bay is Penhallic Point and the one you are now standing on is known as Dennis Point.

    Dennis Point is thought to be a corruption of the Cornish word dinas meaning "castle". An area on Penhallic Point opposite is also known as "Dennis Scale" which is thought to have similar origins. Clifftop forts on top of headlands such as this were common in the Iron Age. However no evidence has so far been found that there was a fort on either headland, so it remains an unsolved mystery. Whether there's any connection to the old name Trebarrow used for Trebarwith Strand is also not clear. The name "Dennis" crops up elsewhere in Cornwall such as Dennis Hill at Padstow, which is thought to get its name from the rocky outcrop on the hill that looks a bit like a fort.

  39. When you reach the waymark, bear left and cross the stile. Follow the track to the Port William pub to reach a small path with a coast path sign departing to the right.

    The main building of the Port William Inn is recorded in its present location on OS maps from the 1880s but no use as a public house is recorded in this period. The more recently-added outdoor terrace and conservatories offer spectacular views of the beach and coastline for weary walkers to enjoy some well-deserved refreshment. The interior is decorated with various trophies recovered from ship wrecks such as brass propellers, lanterns and even half of a rowing boat!

    A track shown on the 1880s maps ran past the buildings all the way to Port William beach and this was still usable in the 1980s. The 1973 film "Malachi's Cove" was filmed on the track and the beach. Since then, a cliff fall has buried part of the track near the beach and more recently a section of the track closer to the pub has been undermined by the sea so it is now closed to the public.

  40. Follow the signposted Coast Path down to the road at Trebarwith Strand.

    Trebarwith Strand is in the centre and is the lifeguard-patrolled area. It's sandy on the left and, to the right side, there are more rocks including some good rock pools. The large pool beside the rocks on the right side of the beach is known as "Horse Pool" from when horses were used to transport slate and sand, and this provided somewhere for them to cool off from their heavy work.

  41. Take the public footpath on the right of Trebarwith Surf Shop. Follow the path up to the cliff top to reach a waymark at a junction of paths.

    If the tide is out, there are some rockpools on the right-hand side of Trebarwith Strand towards Lill Cove.

    Rockpool fishing is quite a popular childhood pass-time as a number of species can be lured out from hiding places by a limpet tied on a piece of cotton (leave a trailing end as if anything swallows the limpet, very gently pulling both ends of the cotton will cause it to release the cotton-tied limpet from its gullet). If you are intending to put the creatures into a bucket: ensure it is large, filled with fresh seawater and kept in the shade; ideally place in a couple of rocks for the creatures to hide under; do not leave them in there more than a couple of hours or they will exhaust their oxygen supply; ensure you release them into one of the rockpools from which you caught them, preferably a large one (carefully removing any rocks from your bucket first to avoid squashing them). Species you're likely to encounter are:

    • Blennies which are fish about 5-10cm long, often found hiding under rock ledges. They can change their colour from sandy to black within a couple of minutes in order to match their surroundings. They have strong, sharp teeth for crunching barnacles and will bite if provoked.
    • Shore crabs and sometimes edible crabs which can also sometimes be found hiding under rocks (carefully replace any rocks you lift up). Shore crabs have a fairly narrow shell which is almost as deep as it is wide. They vary in colour from green through brown to red (the redder individuals are apparently stronger and more aggressive). Edible crabs have a much wider shell which resembles a Cornish Pasty and are always a red-brown colour. Both have powerful claws so fingers should be kept well clear.
    • Shrimps and prawns - do you know the difference? Prawns are semi-transparent whereas shrimps are sandy coloured and generally bury themselves in sand.
  42. When you reach the waymark, follow the middle path (indicated by the yellow arrow and acorn) up the steps. Continue to where the paths rejoin and a few paces further to reach another waymark.

    In 1886, an iron-hulled sailing ship, named the "Sarah Anderson", got into difficulties off Tintagel Head in a violent gale then blew up and sank off Trebarwith Strand. According to one source, the ship was carrying a cargo of 966 tons of manganese ore and 15 tons of dye. According to another source, it was hinted that she might also be carrying copper, silver and gold. Due to the huge waves, the Port Isaac lifeboat was unable to launch and the ship was out of range of the marine rescue rockets brought to the shore at Trebarwith Strand. All the 14 crew and 4 passengers (2 women, including the captain's wife, and 2 children) perished. Divers report that the hull is now almost entirely gone. One section (presumably the stern) stands about 3m high and is separated from the main wreckage; the remainder consists of the ore cargo with the odd piece of steel protruding.

  43. At the waymark, follow the path left, up the steps, until you reach another waymark at a junction of paths.

    The beach at the bottom of the cliff to your left is Lill Cove.

    A small water-powered copper mine existed on the cliff slopes above Lill Cove and was worked until the early-mid 19th Century. A hollow in the cliff was dammed to form a reservoir which was fed by a leat; the reservoir in turn was used to drive a waterwheel to pump out the groundwater draining into the mineshaft. Little remains now as some massive landslips on this part of the cliff have obliterated the majority of the mine workings.

  44. At the waymark, bear left in the direction indicated to Tintagel and follow the coast path up to the rock outcrop. From the top continue along the cliff until you reach another waymark (to Treknow) at the start of the coastal quarries.

    Coastal slate quarries are confined to a small area of about five miles either side of Tintagel and relatively little is known about their history. In order to work the vertical cliff face, strong points were built from stone above the working areas. From these, ropes were dropped down the quarry face. Men were lowered down the faces on these ropes to split blocks of slate from the face. The slate was hauled up the cliff face on these cables which were wound using "horse whims" - capstans powered by horses or donkeys walking around a circular platform. The stone was split and shaped on "dressing floors" on the cliff top, originally covered with sheds. The remains can be seen as level terraces and are marked by screes of waste rock on the cliff below. Splitting was (and still is) done with a bettle (hammer) and chisel, hence the name of the pub in Delabole.

  45. At the waymark, continue straight ahead on the coast path passing the rock pillars at West quarry and follow along the wall behind Lanterdan quarry until you reach a waymark for Tintagel, just before a track departing to the right.

    There are 9 slate quarries along the coast path between Tintagel Church and Trebarwith Strand. Slate quarrying began here in the early 14th Century and ended just before The Second World War. The slate was exported from Tintagel Haven and later from boats moored along Penhallic Point.

    Cutting the stone and loading it onto boats was harsh work and could be lethal. A local man - Alan Menhenick - recalled in the 1920s: "we worked with the tides, around the clock. I've been at the quarry at four in the morning. When the tide was in, we blasted; when the tide was out, we went down and collected the slate". In 1889, three men vanished into the sea when the face that they were boring sheared off the cliff.

  46. Continue straight ahead at the waymark, past more of Lanterdan quarry and along the edge of a wall to a stile.

    The Lanterdan and West quarries above Vean Hole and Hole Beach at Trebarwith Strand were once some of the biggest in North Cornwall. In Lanterdan quarry there is a tall, distinctive, pinnacle of rock. This was left behind as the slate in the pinnacle was not of a sufficiently good quality; shorter pinnacles were left in West Quarry for the same reason. These chunks of inferior-quality slate were known locally as "scullocks".

    The quarry workings never reached the shoreline as there is a fault along the base of the quarry, known as the Trambley Cove Formation. This is made of volcanic lava which was no good to the quarrymen. Lanterdan Quarry is now owned by the National Trust and is a site of geological interest for two reasons. The first is that it contains brachiopod (shellfish) fossils. Second, a rare mineral called monazite is present which contains rare-earth (lanthanide) metals.

  47. Cross the stile and follow the path to a waymark beside a stone stile. Continue on the coast path around the cliff edge to another waymark with two yellow arrows where the path forks.

    The vertical cliffs of Hole Beach at Trebarwith Strand were the site of Caroline Quarry. The hole in the cliff, from which the beach gets its name, was excavated to quarry out a chunk of good quality slate. Caroline together with the neighbouring Lanterdan and Bagalow quarries, were some of the last still operating at the start of the 20th century but production had ceased by the Second World War.

  48. Keep left at the waymark, along the coast path behind Hole beach, until you reach a stile in a stone wall.

    The crumbling stone walls and the outlines of buildings are the remnants of Bagalow quarry.

    Bagalow Quarry is located above Bagalow Beach and stretches around to Hole Beach. It dates back to at least the 1800s and was still working at the start of the 20th Century. The quarry face runs from sea level all the way to the top of the cliff. At the top of the cliff are remnants of a powder magazine (some low banks are all that remain) and a horse whim used to haul the slate up from the quarry face.

  49. Cross the stile and go through the gate into a field then follow the fence on the left to a kissing gate in the far left corner before the gateway.

    Ribwort plantain is a common weed on cultivated land with long leaves and unmistakable black seed heads on the end of tall stalks often with a halo of white flowers. Generations of children have worked out that by knotting the stem, the seed head can be launched as a projectile at unsuspecting adults.

    A tea made from the leaves is a popular herbal remedy but care should be taken where the plant is harvested as it is not only highly tolerant of high metal levels in the soil but also accumulates these. It will even tolerate and accumulate arsenic which is normally toxic to plants. It therefore has the potential to be used for cleansing soils contaminated with mine waste.

  50. Go through the gate and cross the stile then follow the path along the wall above the cliffs of Dria quarry on your left, until you reach a kissing gate.

    Dria quarry, between Bagalow Quarry and Penhallic point near Trebarwith Strand, was developed from a natural cove (Dria Cove). The quarry was worked in Victorian times and shown as still working in the 1880s but closed by the early 1900s. No processing areas have been found above the quarry, so it is assumed that this was shared with Bagalow Quarry. The 1880s OS map shows a small platform associated with Dria Quarry but it's possible some of the lifting was also shared with Bagalow quarry. Dria Cove is no longer accessible due to landslips on the cliffs between the two quarries.

    The origin of the name could be a version of tre (meaning farmstead - there are other examples of "Drea" used this way), perhaps referencing a settlement that was once on the cliffs near the cove. There is a low linear bank near the bench on Penhallic Point which is thought to be the remains of a mediaeval field boundary.

  51. Go through the kissing gate and follow the path around to the left towards the bench on the point.

    Penhallic Point is the long headland along the northern edge of the bay at Trebarwith Strand. In the late 1800s, a wharf (which has now been taken by the sea) was constructed at Penhallic Point where the cliff edge was trimmed to form a 100ft vertical face. Ships could lie against this face as there is a natural deep-water berth alongside the point. The slate was lowered by crane down into their holds.

    A path from the top of the point zig-zags down to a grassy platform where there is a lifebuoy. It's possible to get down onto the rocks from here, but only in the summer when the rocks are dry.

  52. From the bench on Penhallic Point, keep right and follow the path along the coast via Higher Penhallic Point to a kissing gate.

    There are quite large clumps of chives at Penhallic Point, near Trebarwith Strand, where the barrier of slate gives rise to clifftop springs (which is why it's used for roofing!). In summer when the chives flower, they attract large numbers of bumblebees and butterflies.

    Wild chives are rare in the UK, but can be found next to the paths and rocky ledges along the cliffs on The Lizard and near Tintagel, particularly where a spring seeps water out across the cliff.

    From a distance, the flowers of wild chives can be mistaken for thrift, but up close they are taller (6-8 inches vs 1-2). Their peak flowering period is also later (July, whereas thrift is May) although there are often some late "straggler" thrift flowers out at the same time. Often chive flowers are more mauve than the pale pink flowers of thrift but there is some colour variation in both towards a more similar vibrant pink. The leaves of wild chives are much thicker (like supermarket chives) and straggly whereas wiry thrift leaves form a tight clump (giving rise to the name "Ladies' cushions"). Perhaps the easiest way to tell them apart is the smell of onions from chives.

    Betony is a grassland herb, common on the coast, with pretty purple anthers that stick out from the plant. The name is derived from the ancient Celtic words bew (meaning head) and ton (meaning good) as it was used as a cure for headaches. From Roman times onward, it was believed to be a cure for a number of things (the Romans listed 47!) including drunkenness. Even as late as the 1800s, Richard E. Banks stated that you should "Eat betony or the powder thereof and you cannot be drunken that day" and John Gerard (1597) said that "It maketh a man to pisse well". Betony was also used to ward away evil spirits (hence it is planted in a number of churchyards) and also to make a dark yellow dye for wool.

    The sea fish known traditionally in the UK as bass, but internationally as the "European seabass" (to distinguish from river species particularly in North America), is a member of the perch family. Given they are normally found in the sea, bass are surprisingly tolerant of freshwater and sometimes venture quite a long way upriver. Bass is very nice to eat but is a slow-growing species and therefore threatened by overfishing. Since 2010, two-thirds of the population has been wiped out in what has been described as "an unfolding environmental disaster" and although there are emergency EU measures in place to restrict both commercial and recreational catches, there is evidence that commercial catches are still well above sustainable levels.

  53. Go through the kissing gate and take the path waymarked for Tintagel to the left. Follow this past more quarry workings to reach another waymark at a fork in the path.

    On the point opposite Tintagel Youth Hostel is the remains of Gull Point Quarry. The quarry face on the rear of the cove was known as Lambshouse Quarry (Lambshouse is the name of the cove). Both were worked in the 19th Century, and jointly for much of their later life. The round platform near the top is the remains of a "horse whim", where a blindfolded donkey used to circle, operating the winding gear.

    The old office, engine and blacksmith's shop of Lambshouse Quarry have been converted into Tintagel youth hostel. You can see the slate waste from the dressing floors on the cliff face below it.

  54. At the waymark, take the left path and follow this until it forks just before a waymark

    Long Grass Quarry on Dunderhole Point was the last working quarry along the Tintagel coast, closing in 1937. It was worked during Victorian times and expanded considerably between 1907 and 1937. A box-shaped cave was tunnelled into the face of the cliff just above sea level and this was accessed via flights of wooden ladders down a sheer cliff face. There are at least two incidents of workers losing their lives here.

  55. Keep right towards the waymark and go up the steps to reach the track to the Youth Hostel.
  56. Turn left onto the track towards the Youth Hostel then bear right to a waymark. Take the small coastal path beside the waymark and follow this to another waymark and remains of a concrete structure. Continue until the path eventually emerges onto a larger gravel path at a waymark.

    The Dunderhole is a 100ft deep split in the cliff face at Dunderhole Point at the end of Tintagel's Glebe Cliff. The name is a corruption of "Thunder hole"; when a big swell is running, the reason becomes apparent. When waves surge into the cavern at the bottom, they compress the air, which then exits through the Dunderhole with a sound that you do not so much hear, as feel resonate through your entire body.

  57. At the waymark, turn left and follow the gravel path until you reach a waymark inscribed Glebe Cliff with a yellow and white arrow.

    The cliffs around the church are known as Glebe Cliffs.

    A glebe was an area of land used to support the parish priest (in addition to a residence in the form of a parsonage or rectory). Occasionally the glebe included an entire farm. It was typically donated by the lord of the manor or cobbled together from several donated pieces of land.

  58. At the waymark, keep right (white arrow) along the gravel path and follow it towards the church until you reach a junction with another path beside a picnic bench.

    Gillow quarry lies part-way down cliffs near Tintagel church, just below a rocky ridge along which the coast path runs before it joins the path from the church to Tintagel Castle. A pair of capstans, known as horse whims, were used to haul slate up from the quarry. A track ran up the cliff beneath the ridge, eventually emerging onto the path to Tintagel Castle. Slate would have been transported by donkey to Tintagel Haven and loaded onto the boats there.

  59. At the church car park, facing St Materiana's church, turn left and follow the path marked "Coast Path and Access to Castle View" until you reach a waymark signposted to Tintagel Castle.

    Tintagel Parish church, dedicated to St Materiana, is located on Glebe Cliff at the end of Vicarage Lane. The first church on the site was thought to be in the 6th century, founded as a daughter church of Minster in Boscastle which is even older. The current church was built in the late 11th or early 12th century with the tower added in the late Mediaeval era. The Norman font bowl by the south wall is believed to have been brought from St Julitta's chapel at Tintagel Castle. The church also contains a Roman stone from the 4th century bearing the name of the Emperor Licinius which may be evidence that there was once a Roman camp nearby.

  60. At the waymark, continue ahead (signposted to Tintagel Castle) until the path forks at the bottom of a flight of steps.

    Tintagel Castle (also known as "King Arthur's Castle") is perched on an island which was joined by a land bridge in the Middle Ages. The ruins of Tintagel Castle that you see today were built in the 13th century by Richard Earl of Cornwall. From coins and pottery fragments found at the site, it is thought that before this, the site might have originally been a Roman settlement, and later, in the early Middle Ages, a Celtic settlement. There is speculation amongst historians that the site was a summer residence for one of the Celtic kings, perhaps leading to the legends of Arthur.

  61. Keep right at the fork (bypasses a steep stile) to reach a waymark and turn left here through the gap in the wall. Follow the path along the wall along the cliff edge to reach a black signpost at the entrance to Tintagel Castle.

    A very large amount of 5th and 6th century Eastern Mediterranean pottery was found at Tintagel Castle in the 1930s, more than the total found in all other Dark Age sites in Britain. This included massive Tunisian oil jars, Carthaginian dishes, Aegean amphorae and Byzantine jars. Some examples are on display in the Royal Cornwall Museum in Truro.

  62. From the entrance to Tintagel Castle you have two choices: You can pay to enter the castle and leave past the steps to the beach and along the fence until you reach the bridge over the stream. Alternatively, you can turn right at the signpost, then left down the steps to descend to the car park; then turn left past the English Heritage shop follow the path downhill reach the tiny bridge over the stream by the fence.

    The small cove at the bottom of the valley is known locally as Castle Beach, although its formal title is Tintagel Haven.

    Below the the island upon which Tintagel Castle is perched, there is a small sheltered pebble beach, known locally as Castle Beach although on maps you'll see it marked as Tintagel Haven. Slate from the coastal quarries was brought here by donkey, and loaded onto beached ships which also brought in cargoes such as Welsh coal. Beside the waterfall is the remains of a derrick which was used to winch the cargo to and from the beach. In order to manoeuvre them around the dangerous rocks, ships were "hobbled" (towed by rowing boats then manoeuvred by gangs of men pulling on ropes).

    On the left side of the beach is Merlin's Cave, and to the back of the beach is a waterfall where the stream running through the Vale of Avalon meets the sea.

  63. Follow the track up from the bottom of the valley until you reach a "Footpath to the village" sign (or to save a climb, you can catch a Land Rover to the top, skipping the next direction).
  64. Bear right onto the footpath signposted to Tintagel Village. Follow it to reach the top of the track.

    The modern-day village of Tintagel was known as Trevena ("place of the women") until the Post Office established Tintagel as the name in the mid 19th century (until then Tintagel had always been the name of the headland and of the parish). In Norman times, a small castle was built at Bossiney; Bossiney and Trevena were established as a borough in 1253 by Richard, 1st Earl of Cornwall who built Tintagel Castle.

  65. Cross the road and turn right. Follow the pavement until you reach the King Arthur's Arms with Tintagel Old Post Office opposite.

    Tintagel Old Post Office is a 600-year-old Cornish Longhouse set in cottage gardens, retaining its mediaeval slate-paved hall and fireplace. It was built in the 14th Century when Tintagel Castle belonged to the Black Prince. In the 19th century, the house was used as the district Post Office when the introduction of the penny post meant the trek to the Post Office in Camelford became too much of a burden. For over 100 years, it has been owned by the National Trust.

  66. Continue along the road from the Old Post Office until you reach the roundabout.

    Just before the roundabout and King Arthur's Hall, look on your left for Aelnet's Cross, which is behind the railings in front of some flats.

    Aelnet's Cross is located on Fore Street in Tintagel next to King Arthur's Great Halls, behind the railings of what used to be the Wharncliffe Arms Hotel (now converted into flats). It is just over 4 feet tall and has a sort of wheel-head cross on both sides along with Latin inscriptions. The cross itself is of the 5th-century, though the carvings and inscriptions could be later (possibly 10th or 11th century). Originally it stood at nearby Trevillet where it was in use as a gatepost.

  67. Continue straight ahead at the roundabout and follow Bossiney Road past the Methodist Church to the Tintagel Visitor Centre.

    King Arthur's Great Halls in Tintagel were built in the 1930s by a custard millionaire whose company is thought to have invented "hundreds and thousands". The Halls of Chivalry are built from 53 different types of stone and are big enough to hold 1000 people. 72 stained glass windows by Veronica Whall (a pupil of William Morris) tell the story of King Arthur and show the Coats of Arms and weapons of the knights. Over two million people have visited the Halls since they opened in June 1933.

Port Isaac is a pretty fishing village with narrow winding alleys running down the steep hillside to the harbour. Particularly noteworthy is the number of 18th and 19th century white-washed cottages and granite, slate-fronted houses, many officially listed as of architectural or historic importance. Port Isaac was a busy coastal port from the Middle Ages to the mid 19th century, where cargoes like slate, coal and timber were shipped in and out. The stone pier was built in Tudor times, and the rest of the harbour in the 19th century. The economy was also heavily based around the pilchard trade.

At high tide, the beach at Port Gaverne is a shingle which is mostly flint - unusual in North Cornwall where most beaches are a golden sand composed of slate and fragments of shell. The reason is that the flint was used as ballast for incoming ships collecting Delabole slate which was brought to the coast by horse and cart. As the tide goes out, a sandy beach is revealed.

Being one of the few sheltered ports on the North Cornwall coast, the beach is used by local fishermen to launch boats and preserving it for this purpose this was a condition of the beach being given to the National Trust by the family that previously owned the beach. Consequently the central area of the beach is not the ideal place for swimming as the rock platforms either side of the inlet give boats very little room for manoeuvre and once a boat coming ashore raises its outboard motor to prevent it grounding on the seabed, it is unable to steer.

The Port Gaverne Hotel was originally the Union Inn frequented by crews of the slate vessels. It was built by shoemaker and fisherman James Stroat who "kept it and then spent all he had". His brother William was a Master Mariner and apparently "a good merry old toper". On the walls of the pub, there are lots of photos and paintings of Port Gaverne and Port Isaac from the 1800s and early 1900s.

According to Arthurian Legend, Merlin lived in a cave below the fortress of Tintagel during Arthur's childhood, and was his teacher. Tennyson made Merlin's Cave famous in his Idylls of King Arthur, describing waves washing infant Arthur to the shore, and Merlin finding him in a sea cave and carrying him to safety.

The cave is 100 metres long and passes completely through the island beneath the castle, where the sea has eroded a fault containing a band of softer rock. At high tide, the cave is flooded (so one can assume Merlin was a good swimmer!), but at low tide you can walk through from Tintagel Haven to the rocky West Cove on the other side.

The rock protruding into the bay at Tintagel Haven, known as "Black Rock", is formed of volcanic lava and metamorphosed version of slate known as phyllite; this has a silvery sheen due to granules of mica formed under greater heat and pressure than slate itself forms under. The black colour is from lichen growing on the surface of the lava.

The valley above Backways Cove is rich in wildflowers and heathland butterflies. Notably a species of wild chamomile grows here which is rare in the rest of the country. There is a story that a cow once went missing for 3 days at Backways Cove and reappeared staggering drunkenly after gorging on chamomile. A chemical within chamomile is known to be an intoxicant in animals if ingested in large quantities, so there may be some truth in this!

The area next to the Spar shop in Tintagel, now called Trevena Square, is on the site of Fry's Coaches. In the 1880s, Fry's ran a horse-drawn charabanc to Camelford and Bodmin. Travel to Tintagel became much easier in 1893 when the railway was extended to Camelford and Fry's provided the connection to Tintagel. For a number of decades, this was horse-drawn, then in 20th century the horses were replaced with motorised coaches and Fry's also became Tintagel's petrol station which closed in 2000.
