St Marys Well Bay (Barry) - Glamorgan

Nestling between Sully Island and Lavernock Point, the bay here is backed by steep cliffs at one end and by dense trees at the other. The terrain is a mixture of sand, pebbles and rocks. At low tide a large area of mud and wet sand is exposed with seaweed-covered stones.

The beach has views over the Bristol Channel towards Avon and Somerset. Also visible from the beach is Flat Holm, a limestone island which is the most southern point in Wales. Steep Holm, the island behind it, is technically in England.

The rocky cliffs behind the eastern end of the beach can be unstable and should be avoided.
