Dive-site story
Situated near the center of Lighthouse Reef, this colossal marine sinkhole opened during past glacial periods when rising seas flooded a dry limestone cave system. The profile requires a rapid descent past the sunlit rim into the cavernous deep, where massive submerged stalactites hang beneath sheer rock overhangs. Sunlight diminishes quickly as you descend, leaving a cathedral-like ambiance accompanied by patrolling reef sharks cruising along the perimeter.
Gigantic prehistoric stalactites suspended beneath deep cavern overhangs
Sheer vertical limestone drop-offs that plunge into the deep abyss
Frequent encounters with Caribbean reef sharks circling near the rim and shelf
