The Donegal. Now there's a name that gets whispers going among UK wreck divers. She’s often touted as one of our favourite wreck dives in Cornwall, and for good reason. What began life as a formidable battleship met its end by German U-boat in 1917, now resting upright on the seabed, remarkably intact. This isn’t just a pile of twisted metal; you can still make out the gun turrets, the bridge structure, and the impressive hull. Dropping down onto the Donegal, you’re greeted by a truly substantial wreck. The sheer scale is what really hits you first. We love exploring the deck guns, now encrusted with plumose anemones and dead man’s fingers. Look for the resident conger eels peeking out from every dark nook. The deeper sections, around 45 metres, are where the bigger fish tend to hang out. It's a site that demands respect and good dive planning, best suited for experienced wreck divers comfortable with deeper profiles and potentially strong currents. Our top tip? Aim for slack water, always. Otherwise, it can be a rocket ride.
Safety Notes
