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) - STANHOLME offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The Stanholme, sunk on Christmas Day 1939, offers a solid dive for anyone keen on a proper steamship wreck off Cornwall. Lying at 19 metres, she’s well within recreational limits, and at 90 metres long, there's plenty of hull to explore. We’ve found her to be a good spot for lobsters tucked into nooks and crannies, and often see pollock hovering around the collapsed superstructure. The boilers are a highlight, still largely intact and a great focal point for photographers. It’s a rewarding dive, especially for those who appreciate the history behind the rust.
