About
A sheltered horseshoe bay on Holy Island with clear turquoise water and a gently sloping sandy bottom that makes it one of Anglesey's safest swimming beaches. The rocky headlands on either side harbour rockpools full of life, and the bay's protection from prevailing winds keeps it calmer than the exposed west-coast beaches. Snorkellers and paddleboarders use the bay year-round.
