Treginnis, on the St Davids peninsula, is the most westerly settlement in Wales, separated from Ramsey Island with its extinct volcanoes near Ramsey Sound.

This walk takes you over the oldest rocks in Wales, from the Precambrian era, which dominate the peninsula. These rocks are volcanic in origin, interwoven in places by layers of younger, sedimentary Cambrian rock.

It’s a great walk at all times of year, whether you’re looking for spring flowers, summer seabirds or some fresh air on New Year’s Day. Watch out for porpoises, seals and intrepid sea-kayakers negotiating the shallow reef known as ‘The Bitches’.

For an added treat, halfway around is the lifeboat station of St Justinian’s, where you can take boat trips to explore Ramsey Island or watch the boats launch.

Did you know that we have a bespoke package designed especially for walkers and hikers?
