Square rock - West Coast
Square Rock, off Ireland's West Coast, gives you a classic Atlantic rocky dive. You’ll weave around boulders and explore crevices, spotting various temperate species like wrasse and gobies amongst the kelp. It’s a good choice for divers looking for a straightforward shore dive, with conditions often calmer than exposed headlands. We'd suggest it for an easy second dive or for newer divers getting comfortable with Irish waters.
