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) - HIGHGATE (POSSIBLY) offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The Highgate is a proper old-school wreck dive, a steamship that went down in 1890, off the coast of Cornwall. At 48 metres, it’s certainly for the experienced among us, a proper technical challenge. We love the way she sits on the seabed, remarkably intact for her age, a true time capsule. The twin boilers are still prominent, standing proud from the main structure, and you can still trace the lines of her iron hull. There's a real sense of history dropping onto the Highgate. The visibility, when it’s good, lets you see a lot of her in one go, a dark shape emerging from the green. We’ve found conger eels tucked into the darker nooks and crannies, and dead man's fingers coral bloom across the metalwork, a soft orange against the rust. If you've got the skills and the gas, the Highgate offers a deep, rewarding dive into maritime history, a quiet, atmospheric exploration of a forgotten ship.
