Description: A general description of the physical features of the dive site

A sheltered narrow inlet popular for both diving and snorkelling. This is a great training site. There are vertical bedrock walls on either side as you enter the cove, which are covered in dense kelp and which have some nice overhangs and swim throughs. The seabed between both walls is sandy, with areas of boulders found at the base of the walls.

Biodiversity: A description of the species composition at the site. Species of interest are highlighted. Follow the links for more information about the species on the NBN Atlas Northern Ireland website

Dense kelp covers much of the bedrock at this site, often with large shoals of fish. The boulders are coated in encrusting and tufted red algae. Look out forsquat lobsters in the nooks and crannies amongst the boulders and overhanging rock.

    Max dive depth: 7.2m, as recorded today

    Entrance/Exit: there is a ladder on the left hand side of the basin which is much easier than trying to navigate the steps and rocks. Tide depending, it allows for either a giant stride entry or climbing down the ladder and putting fins on in the water.

    Loads of catsharks/dog fish as well as urchins, several species of crabs, wrasse and even a few juvenile place in the shallow sandy bed.
