Why dive here
With 169+ marine species recorded in the area - including dolphins, dwarf minke whales, humpback whales, ocean sunfish (mola mola) and octopuses - Illaunabarnagh offers some of West Coast's richest diving. Water ranges 8-17°C, warmest July, August, September.
Illaunabarnagh, off Ireland's west coast, offers a genuine taste of Atlantic diving. We've found the wall dives here reveal a good spread of anemones and wrasse, tucked into rocky crevices. It’s a site that rewards divers who appreciate cool-water marine life and the rugged, natural feel of the Irish coast. If you're looking for something different from the usual tropical scene, this spot delivers.
Safety Notes
Cold water this month (avg 14°C). Drysuit or thick wetsuit (7mm+) recommended.
