Diver's Notes

Cave at 130 ft. Stalactites and stalagmites at mouth of cave. No light needed to see as day light was good enough with such clear water.

Pioneered by Jacques Yves Cousteau in the early 70's, The Great Belize Blue Hole has become Belize's most famous dive site. The hole is a "karst-eroded sinkhole" formed when the roof of a cave, in an underground tunnel complex, collapsed. When sea levels rose at the end of the Ice Age, the once dry cave filled with sea water producing the hole that now measures 1000 feet across with a depth of over 460 feet. It is a Marine Protected Area and a UNESCO World Heritage site. The rim of the Blue Hole and the surrounding lagoon is only a few feet deep and excellent for snorkeling.

As you descend over the edge, through a thermocline at around 50 feet, big groupers, snappers and horse-eye jacks come to investigate. Deeper still, with your eyes adjusting to the low light, black tip sharks can be seen slowly patrolling the depths. At approximately 110 feet, the first limestone ledge appears and immense stalactites hang from the ceiling. On your slow ascent back to the edge of the hole, spotted morays can be found in crevices and on the wall crest, you return to the domain of the parrotfish and angelfish.
