The Four Mile Bridge and Rhoscolyn Loops
These two routes build on the Trearddur loop and take us to the southern part of Holy Island. As we move away from the sea the landscape changes to open pasture and traditional Welsh cottages. Both routes eventually take us across the ‘Four Mile Bridge’ and back to Anglesey.

The Rhoscolyn Loop differs with a detour to the most southerly village on Holy Island – Rhoscolyn. Rhoscolyn has its own beautiful sandy beach – Borth Wen – along with a lifeboat station. The local church has a memorial to the Lifeboatmen who lost their lives around the coast of Anglesey whilst trying to save others. The village is also home to renowned The White Eagle bar/restaurant – reportedly a favourite of William and Kate, the Duke and Duchess of Cambridge.

From Valley the route follows the old A5 trunk road (don’t worry there’s a separate cycle lane) and back into Holyhead itself.

Even including a detour to South Stack lighthouse the longest route is only barely twenty miles. However, given the terrain – and allowing plenty of time to stop and explore along the way – we’d suggest that you set aside a full day.
