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) - Countess of Erne offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The Countess of Erne is a site we’ve returned to time and again, and it rarely disappoints. Lying at just 13 metres, she’s a fantastic introduction to wreck diving in UK waters, especially for those still building confidence. We love how much of the wreck is still recognisable, even after sinking in 1935. You can still make out the paddle steamer’s wheels, two huge structures now completely encrusted with plumose anemones, waving gently in the current. Swimming through the collapsed superstructure, you’ll likely spook a few pollack, darting between the metalwork. Our favourite spot is usually around the bow, where crevices offer shelter to spider crabs and blennies. The visibility here can be classic UK – a bit green, a bit murky – but on a good day, when the sun filters through, the light plays beautifully on the anemones and dead man’s fingers. We’d suggest timing your dive for slack water to really enjoy poking around without fighting a current. It’s not a deep dive, but there’s enough to explore for a solid 40 minutes, making it a brilliant spot for multiple dives in a day.
