HMS Transylvania
Why dive here
With 169+ marine species recorded in the area - including dolphins, dwarf minke whales, humpback whales, ocean sunfish (mola mola) and octopuses - HMS Transylvania offers some of West Coast's richest wreck diving. Water ranges 8-17°C, warmest July, August, September.
The HMS Transylvania wreck is one of those dives that feels like a real pilgrimage. She was a grand liner, then a WWI armed merchant cruiser, sunk by a U-boat in 1917. Now she rests in deeper water off the West Coast of Ireland, a truly impressive hulk. We typically find the conditions here can be challenging, with strong currents and reduced visibility not uncommon, but on a good day, it’s absolutely worth the effort. Dropping down onto her, the sheer scale hits you. This isn’t some small fishing boat; it’s a substantial liner, her structure still remarkably intact in places. We’ve found the stern section particularly interesting, with huge prop shafts and rudder components still visible. It’s a proper expedition, exploring the debris field and penetration points for those with the right training and gear. You’ll spot conger eels in the deeper crevices, and often schools of pollack hanging over the superstructure. It's a dive for experienced wreck divers who appreciate history and don't mind a bit of a challenge. Our pick for when you want a dive that truly tests your mettle and rewards you with a tangible piece of history.
