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) - ONEGA (POSSIBLY) offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The Onega, a big old steamship from 1880, sits upright in around 31 metres of water off the coast of Cornwall. We love a wreck with some history, and this one, originally the British Queen, has had a few names in her time before she went down in 1918. You'll drop onto a truly substantial vessel, 122 metres of broken metal, and the sheer scale is the first thing that hits you. The stern, in particular, is a favourite section of ours for exploring, with its rudder still intact and the propeller blades often visible in decent visibility. Inside the hull, you'll find the three boilers, now home to plump conger eels that peer out from the darkness. We’ve had some fantastic dives here, often spotting dogfish tucked into crevices and schools of pollack circling the higher points of the wreck. It's an atmospheric dive, especially when the light filters down through the green water. Current can pick up, so we always suggest timing your dive for slack water to make the most of the penetration opportunities. This is a dive for experienced wreck enthusiasts who appreciate the bones of a ship.
