Local tip
The lane is narrow and the car park small, so allow extra time and consider a quieter day.

Borthwen is a small sandy bay on the south side of Rhoscolyn, on Holy Island. The Anglesey Coastal Path (part of the Wales Coast Path) passes through Rhoscolyn. A lifeboat station operated here from 1830 until 1929.

What to see and do

The beach car park is the start and finish of Visit Anglesey's Rhoscolyn Circular Walk, about 5.8 miles, graded moderate. It follows low cliffs to the rock arches at Rhoscolyn Head (Bwa Du and Bwa Gwyn), passes St Gwenfaen's Well and church, and looks out to Ynysoedd Gwylanod, where you may see seals. The route includes some quiet roads and farmland.
