Why dive here
With 185+ marine species recorded in the area - including blue sharks, dolphins, dwarf minke whales, humpback whales and ocean sunfish (mola mola) - Wreck of HMHS Llandovery Castle offers some of South Coast's richest wreck diving. Water ranges 9-15°C, warmest July, August, September.
The Llandovery Castle isn't just a wreck; it's a piece of history, deep and demanding, and for us, that’s precisely its appeal. Dropping onto the deck of this Canadian hospital ship, sunk by a U-boat in 1918, is always a profound experience. You’ll feel the chill even through a thick drysuit as you descend into the green gloom, the enormity of the vessel slowly revealing itself. We love tracing the outline of her superstructure, imagining the lives onboard. The wreck itself is home to some incredible life. We've often spotted elegant cuttlefish tucked into crevices and always keep an eye out for the resident anglerfish, masters of camouflage. The deeper sections attract larger cod and schools of blue whiting, sometimes so dense they momentarily block your view of the wreck. This isn't a dive for beginners; strong currents are common, and the depth requires careful planning and experience with decompression. But if you're prepared for a serious dive, the Llandovery Castle delivers a haunting, unforgettable journey into the past.
