    StandoutExceptional marine biodiversity

    The Glenart Castle isn’t a shallow, easy dive. This is proper temperate wreck diving, often with a decent current pushing through. What we love about it, though, is how she really feels like a piece of history. You’re not just looking at metal; you’re looking at a ship that served as a hospital during WWI, and that context adds a real layer to the dive. The wreck lies broken but still recognisable in parts, with big plates of steel creating overhangs and crevices that are just bursting with life. We’ve finned past schools of whiting so dense they silver the water, and often spot common cuttlefish tucked into nooks. Keep an eye out for boarfish, their bright colours a nice contrast against the dark steel. It’s a site for experienced wreck divers who appreciate the story as much as the structure, and who don’t mind a bit of a challenge for the reward of exploring a true historical vessel.
