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
A path climbs from the road onto the ridge and reaches the fort, with the option of continuing to the higher summit of Yr Eifl. Steep and rocky underfoot but never technical.
Worth knowing
- The hut circles are the point. Walk inside the walls and you are standing in a town that was occupied for six hundred years.
- Do not move or climb on the stonework. It survives because people have largely left it alone.
- Fully exposed with sea on three sides. Windy far more often than not.
What you’ll see
Hut circles and rampart walls, the Llŷn peninsula stretching away, and Eryri across the water.
Background
Tre’r Ceiri, the town of the giants, was occupied from around 200 BC into the Roman period. Its survival is exceptional because the site was never farmed or quarried.
