    StandoutExceptional marine biodiversity

    The Cavallo is a proper deep dive, sitting at 53 metres, so this one's for the experienced technical divers among us. We love the solemn history of this steamship, torpedoed in 1918 by a German U-boat. Dropping down, you hit the bow first, often enveloped in a shroud of silty green light. The visibility here can be tricky, so pick your day carefully, ideally on a neap tide for less current. The wreck itself is largely intact, with the main deck housing a dense population of plumose anemones, their white tentacles swaying like ghostly fingers in the deep. We’ve spotted conger eels tucked into the collapsed sections of the hull, and schools of pollock often mill about the superstructure. Exploring the engine room is a highlight, but be mindful of the silt and your buoyancy. This site truly gives you a tangible connection to maritime history. Come prepared for a serious dive; it’s cold, it’s dark, but the rewards are there for those who respect its depth and its past.
