HMS VIPER - Cornwall & Devon

The HMS Viper wreck, tangled among the rocks off Alderney, is a surprisingly engaging dive for such a shallow site. We're talking just 4m here, which means incredible bottom time and great light penetration on a sunny day. She was a torpedo boat destroyer, a cutting-edge vessel for her time, and it’s a bizarre feeling to drift over history so close to the surface. What’s left of her is spread out, a jumble of metal plates and twisted girders that tell a story of a ship that ran aground during maneuvers in 1901. We love exploring the scattered pieces, imagining the chaos that must have ensued. Even with the limited structure, there's a real sense of history. Because it’s so shallow, the light really plays across the seabed, highlighting the anemones and small crabs that have colonised the metalwork. You'll find plenty of wrasse darting in and out, and we’ve spotted small schools of pollock congregating around the larger sections. It’s a perfect site for newer divers looking for their first wreck experience, or anyone who just wants a relaxed, long dive with a bit of historical intrigue. The easy depth means photographers get fantastic natural light, too.
