    StandoutExceptional marine biodiversity

    Gregory’s Sound, off Ireland's west coast, offers a straightforward dive down to 15m. It’s a good spot for newer divers to get comfortable in cooler waters, with manageable conditions. You'll likely find a good variety of the usual Irish suspects here: crabs scuttling over the rocky bottom, some kelp swaying with the gentle surge, and perhaps a curious blenny or two. We'd suggest it as a relaxed intro to diving in the region.
