Where it is
The circle shows the general area, not the exact start. Use the directions link below to get to the car park itself. Contours and paths shown are OpenTopoMap, drawn from OpenStreetMap data.
The route
From Ty Mawr, paths climb the heath to Caer y Twr on the summit, returning by the coast side. Rocky underfoot near the top.
Worth knowing
- The hut circles at Ty Mawr are free and unusually complete, with walls waist high.
- Caer y Twr on the summit encloses the top with a stone rampart and a Roman watchtower base.
- On a clear day the Isle of Man, Ireland and the Lake District are all visible.
What you’ll see
Stone hut circles, the summit rampart, the Roman watchtower, and a huge sea view.
Background
The huts were occupied from the Neolithic into the Roman period. The watchtower on top was part of the Roman coastal defence against Irish raiders.
