Why dive here
With 169+ marine species recorded in the area - including dolphins, dwarf minke whales, humpback whales, ocean sunfish (mola mola) and octopuses - Gleninagh pier offers some of West Coast's richest reef diving. Water ranges 8-17°C, warmest July, August, September.
Gleninagh Pier, on Ireland’s West Coast, offers a surprisingly sheltered dive. Under the pier's shadow, we found crabs, blennies, and the occasional dogfish tucked into the rock crevices. It’s a straightforward shore entry, making it a good spot for newer divers or those looking for a relaxed second dive. Visibility here can vary a lot, so we’d suggest checking local conditions before you go.
Safety Notes
Cold water this month (avg 14°C). Drysuit or thick wetsuit (7mm+) recommended.
