The walk crosses fields from Bossiney to reach St Nectan's Glen. The route follows the glen alongside the river to reach St Nectan's Kieve (waterfall) and then continues upstream to the top of the valley. The route then follows the other side of the valley through the wildlife area created from the slate tips of Trevillett Quarry and paths used by Victorian quarrymen. The walk re-enters Tintagel from Trenale with views all the way to the coast.


  • Woodland walk through St Nectan's Glen
  • Pretty waterfall at St Nectan's Kieve
  • Panoramic views over Tintagel and St Nectan's Glen from Trewinnick


  • The route includes 300m stretch of a C-road where some traffic should be anticipated. The last 100m of this has a verge.
  • The field at direction 22 is marshy although less so in long, hot summers.
  • The field at direction 22 gets quite a lot of late spring and summer vegetation growth. At this time of the year, a stick and secateurs are likely be useful to clear the way both for yourself and other walkers that follow in your footsteps. Previous/subsequent fields are grazed which should keep vegetation in check.
