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.
