    StandoutExceptional marine biodiversity

    We’ve always had a soft spot for the Landrail, even with the "probably" tacked onto its name. This isn't a sleek, intact warship; it’s a proper demolition job, a stark reminder of its target practice past. Lying at 30 metres, the torpedo boat destroyer is heavily broken, but that's precisely its charm. You'll descend onto a scatter of metal, plates, and twisted girders, all beautifully colonised by plumose anemones and dead man's fingers. Our favourite part is picking through the debris, spotting the tell-tale shapes of what was once a powerful vessel. Look for the engine block, a big, hulking piece of machinery that’s still very much recognisable. There's a lot of life here too, even without official species counts. We often find conger eels tucked into the larger sections and schools of pouting weaving through the structure. Visibility can be a bit hit-or-miss, as with much of the UK, but on a good day, the light filtering through the anemones is something else. It's a dive for those who appreciate history and the way the sea reclaims its own, rather than a perfectly preserved wreck.
