    Gary's Wall is one of those spots where Grand Cayman really shows off. The mooring pin sits a bit deeper, around 25 metres, and then the wall just falls away. We love how the reef forms these dramatic fingers, with sandy channels carving paths between them, almost like underwater canyons. The coral formations along the top are a real highlight, full of overhangs that beg for a closer look. We’ve seen plenty of interesting things tucked into these nooks – Caribbean chestnut morays peering out, and often little blackfin blennies or roughhead triplefins hiding in plain sight. Keep an eye out on the sand for a sand stargazer, they're always a treat. Visibility here is usually excellent, around 24 metres, which makes drifting along the wall feel incredibly expansive. It's a superb dive for anyone who appreciates the drama of a sheer drop-off, offering chances to spot larger pelagics passing by in the blue, or just to spend time hunting for the smaller, more unusual critters hiding in the wall's many crevices.

    Safety Notes

    Wreck site - avoid penetration without wreck diving certification. Watch for sharp metal and entanglement hazards.
