Why dive here
With 169+ marine species recorded in the area - including dolphins, dwarf minke whales, humpback whales, ocean sunfish (mola mola) and octopuses - ST OLIVER offers some of West Coast's richest wreck diving. Water ranges 8-17°C, warmest July, August, September.
The St. Oliver, a fishing vessel built in Dingle in 1975, met its end on the rocks of the Aran Isles in 2004. We're looking at a wreck here, about 19.8 meters long, lying shallow enough that its hull or superstructure still breaks the surface. It’s a somber site, a reminder of the sea’s power, but beneath the waves, life finds a way. Expect to see the typical Irish cold-water residents - wrasse darting through the broken timbers, maybe a conger eel peeking from a dark crevice. This is a site for those interested in maritime history and how wrecks become artificial reefs; it’s not about vibrant corals, but the stark beauty of a man-made structure reclaimed by the ocean.
Safety Notes
Wreck site - avoid penetration without wreck diving certification. Watch for sharp metal and entanglement hazards.
Cold water this month (avg 14°C). Drysuit or thick wetsuit (7mm+) recommended.
