Why dive here
With 176+ marine species recorded in the area - including blue sharks, dolphins, dwarf minke whales, humpback whales and ocean sunfish (mola mola) - UNION offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The Union, an old sloop that went down off St. Martin's Point back in 1889, now rests at 37 metres. It's a proper British wreck dive, dark and often a bit silty, but rewarding if you like a proper exploration. You'll find plenty of crabs tucked into the nooks, and the occasional dogfish patrolling the edges of the debris field. We'd suggest this one for experienced divers who enjoy navigating a slightly broken up wreck rather than a fully intact vessel.
