Stack Rocks (Elegug Stacks)

About this site

The Elegug Stacks off Pembrokeshire's Castlemartin Peninsula are dramatic limestone sea stacks surrounded by shallow reefs ideal for beginner and intermediate divers, with grey seals hauling out on the rocks above and exploring underwater alongside divers. Nesting guillemots and razorbills create an unforgettable above-water spectacle while the reef below teems with wrasse, anemones, and crustaceans.
