Dive-site story
Located along the rocky shoreline of Portstewart in County Londonderry, this natural inlet serves as an accessible entry point for exploring the North Coast's kelp-covered basalt formations. Divers navigate out from the sheltered pool through rocky channels that open onto sandy patches and boulder slopes exposed to the open Atlantic.
Rugged basalt gullies and crevices filled with crustacean life
Kelp canopy hosting schools of juvenile Atlantic fish
Sheltered pool entry offering straightforward access during calm weather
Location
Use the map to plan with your operator and confirm the exact entry point on the day.
Seasonality
Warmer water temperatures and calmer sea states make late spring through early autumn the most reliable window for diving here.
