Known as one of the best dive sites in the world, the Blue Hole Natural Monument has become a diver's pilgrimage. At 406.9 feet in depth and 1,049.8 feet in diameter, this collapsed cave is said to be a sediment trap, offering explorers excellent historical discoveries.
As an established natural monument of Belize since 1996, this cave forms part of the Lighthouse Reef Atoll, rich in marine diversity, particularly endangered species, though the Blue Hole itself contains few marine life.
Exploring its depth is not easy. The Blue Hole is compared to swimming down a mineshaft; hammerhead sharks inhabit this mineshaft. Not for the faint of heart for the serious diver, the Blue Hole is a challenging adventure.
