    StandoutExceptional marine biodiversity

    The Greatham, just off Bolt Head, is one of our absolute favourite wrecks in this corner of the UK. We love the way she sits upright, two massive boilers still dominating the midships, even after all these years since she went down in 1918. Dropping onto the deck, you’re often greeted by schools of pollock, weaving through the superstructure, a silver flash in the green light. The bow is a real highlight, still very intact, and it feels like stepping back in time when you peer into the hold spaces. It's a deep dive, down to 40m, so definitely one for experienced divers comfortable with the chillier water and sometimes brisk currents. Visibility can range from glorious 15m to a more typical 5m, but even on the murkier days, the sheer scale of the Greatham makes her an impressive dive. Look closely around the plates for nudibranchs, and the occasional lobster peeking out from under a bulkhead. A slack water dive is always best here; try to hit it just before the turn for the most relaxed exploration.
