- Recreational boat traffic and moorings nearby. The site is quite exposed to the east and there can be litter in the bay.
This site is great for both diving and snorkelling. There are two entry options, either to the south of the beach (for the seagrass bed) or to the north of the beach. The seabed at the southern end of the beach is made up of gently sloping fine sand with areas of seagrass bed about 100m off the shoreline. At the north end of the beach, there are rocky outcrops with dense kelp.
The shallow sandy seabed supports a bed of seagrass Zostera marina. Seagrass beds are listed as a priority habitat in Northern Ireland due to the important role they play in carbon sequestration, sediment stabilisation and provision of nursery grounds for many marine species. Look out for juvenile fish, spider crabs and stalked jellyfish. At the northern end of the beach, the rocky outcrops are covered in kelp, while a variety of fish, bobtail squid and crabs may be seen on the sandy seabed below.
