    StandoutExceptional marine biodiversity

    Illaunloo, off Ireland's west coast, offers a genuine taste of Atlantic diving. We've often found sturdy kelp forests here, swaying with the swells, and the rock formations create some interesting swim-throughs, if you poke around a bit. Expect to see the usual suspects for this region: wrasse, pollack, and sometimes a curious seal gliding by. It’s a good spot for divers comfortable with cooler water and keen on exploring temperate marine environments.
