The Great Blue Hole





This natural sinkhole lies 60 miles off the coast of the Central American country of Belize. Formed when sea levels were much lower, it was originally a limestone cave.
As sea levels rose, the cave collapsed, leaving a hole more than 300 metres across and 125 metres deep. Jacques Cousteau declared it one of the best dive sites in the world.
