From the air it's a dark blue eye opened in the middle of the Caribbean turquoise. The Great Blue Hole is a perfect underwater sinkhole, 318 meters across and 124 meters deep, and one of the most coveted dives on the planet. You descend along vertical walls until you reach giant stalactites — proof that this was a dry cave thousands of years ago — while reef sharks glide by in the gloom. A World Heritage Site. Only for divers hungry for the myth.
