The walk begins beside the Court House and follows the leats to their source on the River Kenwyn. The walk then follows the Kenwyn Valley through New Mill to the woods at Treworder and crosses into the tributary valley at Roseworthy. The route returns along the tributary valley via Penrose Water Gardens to Ninnis at the confluence of the streams. The return to Truro is via Victoria Gardens.

One of the paths runs along the top of a bank and involves climbing over/between tree trunks.

Directions

  1. Make your way to the Court entrance and walk down the hill opposite until you reach a staggered pedestrian crossing with a black metal bollard.

    A Norman castle was built near the confluence of the Rivers Allen and Kenwyn and the small town of Truro grew beside this. By the beginning of the 14th Century, Truro was an important river port until trade collapsed due to a recession brought about by the Black Death and this resulted in the town being largely abandoned. During the Tudor and Elizabethan periods, trade returned and the town grew. During the mining boom of the 18th and 19th centuries the town prospered and was known as the "London of Cornwall" in Victorian times. Following the building of the cathedral, it was granted city status in 1877 by Queen Victoria and is the only city in Cornwall.

  2. Turn right to follow the path along The Leats. Continue ahead over a bridge with iron railings and between the walls to emerge onto a road.

    The open leat system running through the streets of Truro was created by the Victorians to supply drinking water for horses and for washing down the streets. Along many sections of the leat are steel eyes set into the granite using lead, which are thought to be where horses were tied up when people visited the shops. The leats were originally fed by the weir gate system below Victoria gardens. Water is now extracted without a gate to minimise the risk of flooding.

  3. Cross over Hendra Road and turn right to follow St George's Road beneath the viaduct. Keep following the road to reach a bend with a sign for Bosvigo.

    The main line railway through Cornwall was originally conceived as a means to link the port of Falmouth to London. However, whilst funds were being raised for the railway, much of Falmouth's Packet trade was transferred to Southampton. The line was built to Truro instead but initially failed to make money and was bought up by Great Western. Once established, the new railway allowed rapid exports of perishables to London including fresh flowers and fish. It also made large-scale tourism possible and the term "Cornish Riviera" was coined.

  4. Keep left to follow the road around the bend a short distance to where a footpath departs from the right through a metal kissing gate immediately after the 20 zone sign.

    Although it has become a perjorative nickname for tourists, the term "emmet" (from a Cornish dialect word for ant) was originally used quite generally to refer to a crowd of people seen from a distance. In the 18th and 19th centuries, the quarrymen scaling the cliffs on ropes were referred to as emmets. In Victorian times when tourism to Cornwall became popular, the term was also applied to the tourists on the beaches, seen from the cliffs. As quarrying either became uneconomical or mechanised, the large numbers of workers on the rock faces vanished and now use of the term for tourists is the only one surviving.

    Prior to Victorian times, visitors had been coming to Cornwall in small numbers for hundreds of years and consequently the Cornish language also contained a perjorative word for the less gracious of these: tervyajor, which transliterates to "tumultous voyager" i.e. "disruptive visitor".

  5. Go through the gate on the right and follow the path into the woods to reach a fork near the stream.
  6. Keep left at the fork and continue on the path to reach a gate ahead.

    Wild garlic grows along the shady areas of the path near the stream.

    Wild garlic has been found in settlements dating as far back as the neolithic period which given its springtime abundance and aroma is not that surprising. Its culinary use was eventually overtaken by domesticated garlic which first arrived with Mediterranean traders and had the advantage that the bulbs could be stored for relatively long periods.

  7. Go through the gate and cross over the bridge and follow the path to a stile.

    The settlement of Coosebean is Cornish for "small wood" and was first recorded around 1400. There was a mill here which was originally a "blowing house" used for smelting ore. During the 19th Century it was converted into woollen mills and paper mills. By 1827 it was one of the largest paper mills in Western England and employed 40 people but was destroyed by a fire in 1848. After this it was rebuilt as a corn mill.

  8. Cross the stile onto a track and turn left to reach a road. Turn right onto the road and follow this until you reach a stile on the right.

    There are some nice examples of herringbone walling along the lane. At the end of the wall on the right just before you reach the stile, look out for a Celtic cross shape built into the stone tower at the end of the wall.

    The "herringbone" style of walling built with tightly packed alternating diagonal slate courses, is unique to Cornwall's heritage. It is known locally as "Jack and Jill", "Curzy Way" or "Kersey Wave". The latter two names are based on the Cornish word kersy which means "reeds", perhaps referring to a square weave pattern. On a long wall, the herringbone sections are often between "towers" of flat-laid slate (built from the larger and squarer stones) which helped to prevent the wall slumping sideways. Traditionally, hedges (stone boundary walls) were built with whatever was cleared out of the fields, whilst buildings were constructed from stone that was quarried and cut.

  9. Cross the stile and follow the left hedge of the field to reach a stile roughly 20 metres to the right of the gate, leading to a wooded path.

    Blowing houses were mills used for smelting tin and are documented in Cornwall as early as 1402. A pair of bellows was powered by a water wheel, and was used to drive air into a furnace. An account from the late 18th century describes the operation:

    The fire-place, or castle, is about six feet perpendicular, two feet wide in the top part each way, and about fourteen inches in the bottom, all made of moorstone and clay, well cemented and clamped together. The pipe or nose of each bellows is fixed ten inches high from the bottom of the castle, in a large piece of wrought iron, called the Hearth-eye. The tin and charcoal are laid in the castle, stratum super stratum, in such quantities as are thought proper; so that from eight to twelve hundred weight of Tin, by the consumption of eighteen to twenty-four sixty gallon packs of charcoal, may be smelted in a tide or twelve hours time.

    The molten metal drained from the bottom of the furnace into a granite trough from which it was ladled into stone moulds. A stick was inserted into each, which burned away to leave a hole which could be used to lever the ingot from the mould.

  10. Cross the stile and follow the path to reach another stone stile, leading onto a lane.
  11. Cross the stile and turn right onto the lane. Follow the lane downhill to reach a junction on the left just before a ford sign.

    The settlement New Mill(s) was originally known by the Cornish name Melynnewyth which is how it was recorded in 1366. By 1748 it had been translated into English as Newmill. Locally it is still referred to in the singular but it appears pluralised on the OS map. The footbridge beside the ford is thought to date from the 18th Century with the iron railings added in Victorian times. The bridge consists of two clapper sections and a causeway linking them as it crosses both the River Kenwyn and the mill leat.

  12. Turn left and follow the lane uphill past Mill Cottage. Continue for three quarters of a mile to pass Little Canaan Farm and reach a junction with a triangular grassy island.

    The River Kenwyn passes along a culvert beneath the centre of Truro. If this becomes blocked or overwhelmed, the streets in the centre of the town flood and this has happened a number of times over the years. In 1988, Truro was unlucky enough to be flooded twice, seriously damaging the city centre with a cost estimated at £2 million. Following this, flood defences have been constructed around the city, including the emergency dam at New Mill and a tidal barrier on the Truro River. There is also regular cleaning and a debris screen for the culvert to ensure its capacity is not diminished through silting.

  13. Continue ahead at the junction and then keep right to follow the lane around the bend. Continue for a quarter of a mile to reach a track on the right marked with a Public Bridleway sign.

    Particularly if you're doing the walk in summer or early autumn, it's likely that there might be some nettles along sections of the paths for the next two directions. Therefore whilst you're walking along the road, look out for a stick for clearing any in the path later on.

  14. Turn right onto the track and walk a short distance to a waymark on the bridge. Turn right at this to follow the small path along the stream to reach a wooden footbridge just after the shed.

    The footpath for this and the next direction is "silver" status which means it is only cut if reported as needing it. If you spot that the footpath is becoming overgrown, please take a photo and email it to countryside@cormacltd.co.uk together with path number (309/6/1) and location (between Little Treworder and Treworder Farm). They will then get the Parish Council on the case. Thank you.

  15. Cross the bridge and after the wooden walkway, keep right to follow along the top of the bank, passing between the tree-trunks. At the end of the bank, keep right beneath the overhanging tree to join a path between two walls leading uphill. Continue following the path uphill until you eventually emerge on a track beside a farmyard.

    Nettles grow along the area of path below the overhanging tree and on the last section of path before the farm so carrying a stick for this section is advisable. Ensure your fellow walkers are stood well back if you a swinging a stick to avoid raining nettle leaves as well as the stick itself.

    Nettles are extremely nutritious, containing high levels of vitamin A and C, large amounts of iron and even a significant amount of protein. The idea of eating something that can sting you seems wrong until you realise that nettles lose their sting as soon as you cook them, and they taste like spinach. Wearing gloves, strip off the young tender leaves, discarding any large coarse leaves and stems. Use lightly boiled, steamed or wilted as if it were spinach (though not raw unless you want to live dangerously!). All the usual spinach flavour combinations apply (e.g. with ricotta).

  16. Turn left to go through the gate into the farmyard and exit via the gate opposite. Continue a few paces to a junction of tracks and turn left through the wooden gate to the cottages. Keep right to pass the garages and follow the track uphill to reach a gateway into a field.

    The settlement of Treworder dates from the Dark Ages and was first recorded in 1327. Other than Tre- (Cornish for farmstead), the rest of the meaning is not known.

  17. Go through the gate and follow the right hedge of the field until you reach a farm gate on the right just past the pair of telegraph poles.

    The wind turbines to the left are part of the Four Burrows wind farm.

    A typical large onshore wind turbine can produce enough power for about 1,500 houses. The wind turbines being built offshore are a little larger and benefit from it being windier much more often, so one of these is able to power double the number of houses.

  18. Go through the gate and turn left onto the lane. Walk a short distance to reach a gate on the right.
  19. Go through the gate and follow the left hedge of the field to reach a gap in the bottom hedge.
  20. Go through the gap and the gateways and follow the path downhill to emerge onto an area of tarmac.

    Ferns evolved a long time before flowering plants and dominated the planet during the Carboniferous period. The bark from tree ferns during this period is thought to have been the main source of planet's coal reserves.

    Ferns lack seeds as well as flowers and reproduce via tiny spores which are most commonly distributed by the wind. This allows them to colonise some quite random places.

  21. Continue ahead to follow the tarmacked track. Follow this until it eventually ends in a T-junction with a lane.
  22. Turn right onto the lane and follow this to a junction. Keep right at the junction and follow the lane to a junction beside Penrose Kitchen.
  23. When you reach the junction at Penrose Kitchen, pass the entrance then bear right at the junction. Follow the lane over a ford until it ends in a junction.
  24. Keep right at the junction and follow the lane to reach a fork in the lane.

    Bosvean is the Cornish for "small dwelling" which is likely to be a description of what stood there in the early Middle Ages when Cornish was spoken widely. The settlement has gradually spread to create Bussavean (the result of Cornish not being spoken!) and Lower Bosvean.

  25. Keep left at the fork and follow the lane until you eventually reach a sign for a ford at the bottom of a hill beside a junction on the left.

    Ninnis Farm dates from mediaeval times and is from the Cornish an enys meaning "the island" because the farm is situated on a spur of land with rivers either side that meet in a confluence. In 1327 it was recorded in Latin as "De Insula".

  26. Turn left at the junction and follow the lane past Little Coombe to a narrow path with a Public Footpath sign on the right just after the houses.

    The Cornish language has at least 8 different words for "valley".

    • nans - valley
    • golans - small valley
    • haunans - deep valley with steep sides
    • keynans - ravine
    • glyn - large deep valley
    • deveren - river valley
    • coom - valley of a tributary or small stream
    • tenow - valley floor
  27. Follow the path on the right through the gate to reach a kissing gate into a field.

    In August, blackberries start to ripen on brambles.

    Blackberries are closely related to raspberries and technically neither is a berry but an aggregate of many individual tiny fruits, each containing a tiny stone like a miniature cherry.

  28. Go through the gate into the field and cross it to a stile at the bottom of the far hedge where it meets the fence.

    If you are crossing a field in which there are horses:

    • Do not approach horses if they have foals, make loud noises nor walk between a foal and its mother as you may provoke the mother to defend her young. Generally the best plan is to walk along the hedges.
    • Horses will often approach you as they are used to human contact. If horses approach you, do not run away as this will encourage them to chase you. If you are uncomforable with their proximity, calmly walk away.
    • Do not feed the horses with sweets or otherwise. Some food which is harmless to humans can be deadly to horses.
    • If you have a dog, keep it under close control in a visible but safe place, and as still and quiet as possible.
  29. Cross the stile and follow the path ahead through the gap in the bushes to reach a gate and stile into the next field.

    The Birdsfoot Trefoil has yellow flowers tinged with red that look like little slippers and appear in small clusters. They are followed by seed pods that look distinctly like bird's feet or claws. Common names referring to the flowers include 'Butter and Eggs', 'Eggs and Bacon', and 'Hen and Chickens' and to the seed pods the delightful 'Granny's Toenails'.

    It is a member of the pea family and is poisonous to humans (containing glycosides of cyanide) but not to grazing animals and can be grown as a fodder plant. It is the larval food plant of many butterflies and moths including the common blue and silver-studded blue, and an important nectar plant for many bumblebee species.

  30. Cross the stile (or go through the gate if open) and take the lower path. Follow the path across the field to reach a stile.

    Dragonflies were some of the first winged insects to evolve, around 300 million years ago in the "age of amphibians" before the dinosaurs. Fossils of early dragonflies have been found with wingspans of up to two feet across.

  31. Cross the stile and follow the path into a field. Continue through the field to reach a fork in the path.

    Hazelnuts can be found beneath the trees in October and are a favourite with squirrels so you'll need to forage those that haven't already been nibbled. Once harvested, the nuts need to dried before shelling and eating. Wash and dry the nuts first to reduce the chance of them going mouldy. Then lay them out on something where the air can circulate and dry them for 2-4 weeks. An airing cupboard is a good place. You can tell that they are ready when the nuts rattle in their shells. Once shelled, the nuts can be stored in a fridge or even frozen for a couple of years.

  32. Keep left at the fork to reach a waymark. Keep left at the waymark and follow the path through the fields to reach a stile beside the house in the far left corner at the final field.

    Common agrimony is a native plant and a member of the rose family. It prefers less acidic soils which limits its range in Cornwall. It is recognisable by yellow 5-petal flowers on a spike which gives rise to another of its common names: "church steeples". It is also known as sticklewort as the seeds have burs that stick to passers-by.

  33. Cross the stile and follow the track to the road. Turn left and walk a few paces up the hill to a path on the right beneath the bushes where "Slow" is painted on the road.

    Bindweed can normally be spotted in June to September from initially its trumpet-shaped flowers and on closer inspection, being wound around anything and everything. As well as being a nightmare for gardeners and farmers, in the wild it can have a negative effect on biodiversity by choking other native wildflowers and out-competing them for sunlight, moisture and nutrients.

  34. Follow the path from beside the Single File sign. When the path bends to the right and a small path leads ahead, keep right along the hedge and follow the path along a fence to emerge onto a tarmacked road.

    Yellow Archangel is a native plant and member of the dead nettle family (and it's also known as the Golden Dead Nettle). The flowers are pale yellow, hence the first part of the name. The second part of the name (including the angelic association) is because it looks quite like a nettle but doesn't sting.

    A garden variety of yellow archangel known as "aluminium plant" (due to silvery metallic areas on its leaves) has escaped into the wild where it is spreading rapidly. It has been deemed so invasive that it is illegal to plant in the wild.

  35. Turn left to climb the hill and then right at the junction to follow the road until it ends in a crossroads.

    Truro is where Cornish Fairings originated.

    Cornish Fairings are a thin, crisp biscuit flavoured with ginger. Given Cornwall's long trading history, you may be lulled into thinking this was another ancient link with spice merchants but in this case it isn't. The name "fairing" was a word in use throughout England meaning "edible goods bought at a fair" and these included gingerbread as far back as mediaeval times. During Victorian times, biscuits became a popular gift that working class men would buy for their sweethearts, and a number of manufacturers produced ginger biscuits known as "fairings". The Truro baker John Furniss began baking and selling ginger biscuits in his tea room in the late 1800s and these were so popular that they were soon sold by mail order all over the country, establishing the "traditional" Cornish Fairing that we know today. John Furniss' recipe originates from a country fair, possibly from the Launceston New Year "maid hiring" fair.

  36. Cross onto Tremayne Road (signposted on top of the first house on the left) ahead and follow this until ends in a T-junction.

    Our recipe for Cornish Fairings is as follows: Whizz 250g SR flour + 6g bicarb + 8g mixed spice + 7-9g ginger (depending how much ginger heat you like) + 3g cinnamon + 125g golden caster sugar (or similar) with 125g salted butter (or unsalted butter + 3g salt). Tip into a bowl and mix in 150g golden syrup to form a sticky dough. Form into balls about size of chestnuts. Place at least 5cm apart on well-greased baking tray and press lightly to form a fat disc (don't squash too much otherwise they won't develop a craggy surface). Bake for 15-17 mins at 150C (140C in a fan oven) until light brown (darker than golden or they won't be crunchy but be careful not to burn them as they will be darker underneath). Allow to cool for about 2 mins then gently free from trays with a plastic spatula when still warm and soft before they stick, then leave them there a bit longer to harden. Transfer a wire rack to cool fully. Makes 25-30. They freeze very well.

  37. Turn right at the junction and follow the road downhill to reach a track on the left at the end of the railings, just before the park.
  38. Turn left down the track and follow it beneath the viaduct to reach a number of paths radiating into Victoria Gardens.

    The viaduct through Truro carries the main railway line from Paddington to Penzance. The original viaduct was built by Isambard Kingdom Brunel in 1859, but was replaced with the larger granite structure you see today in the early 1900s. Five piers from the Brunel's original viaduct still stand beneath it.

  39. Take the middle path and keep right on it to reach the fountain. Go up the steps on the left of the fountain to the bandstand and up the steps from this to reach an archway in the building.

    Victoria Gardens were created to commemorate Queen Victoria's Diamond Jubilee in 1898. The fountain was originally in Boscawen Street and was moved to the gardens shortly after they opened. A Victorian hydraulic ram raises water from the leats to the top of Victoria gardens which is used to supply the fish pond and cascades though the gardens back into the leat.

  40. Go through the arch and up the steps then follow the path to return to the car park.

    Since at least 1259, and probably before this, there has been a Parish Church of St Mary located on the site of the cathedral. The cathedral architect, John Loughborough Pearson, cleverly incorporated the South Aisle of the 16th-century church into his design. Construction began in 1880 and the cathedral was consecrated and in use by 1887. John died in 1897 and the cathedral was finally completed in 1910 under the supervision of his son Frank who also went on to create a smaller version of the cathedral in Auckland, New Zealand.
