First discovered by Jacques Cousteau, one of the world’s most famous divers and marine conservationists, the Great Blue Hole in Belize is the best of the bunch, and every diver’s dream. Measuring 305m (1,000 ft) across and 123 m (400 ft) deep, the Blue Hole is almost perfectly circular and can be found in Lighthouse Reef Atoll, about 60 miles from Belize City.
Quite lovely this blue hole more than the black hole !
