Three Sisters
A wave-exposed shore dive on the Blackrock headland.
Short cliff access and a V-shaped rocky gap make this a calm-day-only shore dive.
About Three Sisters
Three Sisters is a compact shore dive on the Blackrock headland in Northern Ireland. It sits in a V-shaped rocky gap and only really works when the sea is calm enough to keep the swell down. On the right day it offers a shallow rocky reef with direct shore access and a distinctly weather-window feel, making it better suited to divers who are comfortable choosing their conditions carefully.
