    StandoutExceptional marine biodiversity

    Grand Mal Wall is a site we’ve always enjoyed for its sheer variety, especially considering its fairly shallow max depth of 19m. The top of the reef starts just shy of 2m, then drops off into a proper wall, laced with overhangs and ledges. We love drifting along here, poking into the holes where lobsters often tuck themselves away, sometimes sharing space with a lionfish or two. The real draw for us, though, is the chance to spot those huge tarpon that cruise the deeper edges. We’ve had a few incredible encounters with 2m+ silver kings here; it’s not guaranteed, but definitely adds an extra buzz to the dive. Even without them, you’ll find plenty to hold your attention. Look out for slipperies and barber fish darting through the corals. We’d suggest keeping an eye on your depth here; it’s easy to get absorbed in the shallower parts, hunting for cowfish or spotting a well-camouflaged frogfish if you’re lucky. Visibility averages around 14m, which is decent enough for the wall structure. It’s a good spot for divers who appreciate a mix of macro and the occasional larger pelagic, without needing to go particularly deep.
