    StandoutExceptional marine biodiversity

    The City of Swansea, likely, sits deep off the Cornish coast, a proper technical dive at 40 metres. This isn't one for a quick splash, but if you're comfortable with depth and have the right training, it's a solid day out. We love the way the wreck has settled, largely intact, with a clear list to port that makes exploring the deck a little disorienting in the best way. You'll find the two huge boilers dominating the midships, often draped in dead man's fingers and home to some seriously big conger eels tucked into every crevice. Our favourite detail is the way light filters through the remaining deck plating, creating an ethereal glow around the main structure. Keep an eye out for dogfish patrolling the sand nearby and decent-sized pollack hovering above the superstructure. It's a site that rewards patience and good buoyancy, offering a real sense of history beneath the waves. Best dived on slack water, of course, to fully appreciate its scale without battling the strong tides typical of the area.
