Why dive here
With 169+ marine species recorded in the area - including dolphins, dwarf minke whales, humpback whales, ocean sunfish (mola mola) and octopuses - Galway Quarry offers some of West Coast's richest diving. Water ranges 8-17°C, warmest July, August, September.
Galway Quarry offers a freshwater diving experience on Ireland's west coast. It’s a straightforward site, popular for skill practice and gear testing, often with decent visibility for an inland quarry. Expect to see some introduced fish, though the main draw is the accessible depth and calm conditions. We'd suggest it for training dives or for knocking off the rust after a break.
Safety Notes
Cold water this month (avg 14°C). Drysuit or thick wetsuit (7mm+) recommended.
