I dived it once. It was the first dive after doing an elementary course, there were no grade depth limits then.
Followed the wall down to 30m, dark but not black, saw the start of the stalagmites one large fish and nothing else. We stayed the weekend on Half Moon Cay. The dives around the atoll were much more exciting.
I’ve had the opportunity to dive it 5 or more times since, but not bothered. I’ve even skippered boats out so others could dive it when on Calabash Cay (2 months) then again from Cary Cay (3 months).
