I dove the Blue Hole many years ago. My wife and I were the first guests at Lighthouse Reef Resort in 1989 or so. We dove there for about ten days, as I recall. The reason I mention this is because the reefs were not heavily dived back then. We named most of the sites we dove. So, I don't know what the reefs are like today. I do know for a fact that EVERY dive we did was better than the Blue Hole. We dove the South side of the hole on a small boat. We were the first boat there, because we were staying at Lighthouse Reef. I think another one showed up as we were leaving. There were just the three of us, as it was all week, my wife, me and Bruce, our divemaster. The viz was good, maybe 75-80 feet, as I recall, but definitely not as good as any other dive we did. Every other one of them was virtually unlimited. I think we got down to about 130 feet in the Hole. You really have to go that deep to get a good look at the stalactites and stalagmites. That part of the dive lasts for five minutes or so and the rest of the time was spent off-gassing in the shallows, where there was very little to see. I'm not disappointed we did it. It was a very good novelty dive. If you're diving there the whole week, go see it! If you're riding a boat from the mainland, you would be better off to see any of the fabulous wall sites, particularly Half Moon Caye. It's a world class dive. You can visit the red-foot booby reserve and have lunch while doing a long surface interval before making another wall dive!
