The Great Blue Hole is diving's most recognizable natural wonder — a near-perfect 1,000-foot-wide circle of deep blue surrounded by the shallow turquoise of Lighthouse Reef Atoll. The main event is a descent to 130 feet where massive stalactites hang like cathedral columns in the darkness. While the Blue Hole itself is more spectacle than reef dive, the surrounding atoll offers excellent wall and reef diving.
