Called the Isle of 20,000 Saints, Bardsey lies off the tip of the Lleyn peninsula, from which it is separated by the dangerous Bardsey Sound. The island is about 2 miles long by 3/4 mile broad. It contains the ruins of St. Mary's Abbey, which was founded in the sixth century. Hither fled the monks of Bangor Iscoed when they were threatened by a Northumbrian invasion, to make up the 20,000 saints who are supposed to have died on the island. As a result, Bardsey was for long a place of sacred pilgrimage.
It is a popular place for camping, and can be accessed by the regular boats there from the mainland. An excellent place for an escape, and brilliant for Bird Lovers, Bardsey Island is definately a reccomended place to visit in Wales.
