HMS WARWICK DEEPING - Cornwall & Devon

The HMS Warwick Deeping, a former anti-submarine trawler, sits upright at 35 metres, a proper dive for those who appreciate a bit of history with their nitrogen narcosis. We’ve found her to be a consistently rewarding dive, especially if you catch her on a good day, visibility-wise. The sheer size of her – 47.5 metres long – means there’s plenty to explore, from the stern where the gun mount once sat to the bow, still sporting that impressive 4.7-inch gun. What we love most here is the way the wreck has become a living reef. Dropping onto the deck, you’ll often find conger eels peering from every dark hole, their thick bodies disappearing into the gloom. Jewel anemones cling to the metalwork, a riot of colour in the beam of your torch, and pollack often school above the main structure, their silver scales flashing. Our favourite part has to be the bridge area; it’s collapsed a bit, but still offers some interesting swim-throughs if you're comfortable with overhead environments and good on your buoyancy. Just be mindful of the current, it can pick up, so planning your slack water window is crucial for a relaxed dive. This wreck suits experienced divers comfortable with depth and who appreciate a slice of wartime history reclaimed by the sea.
