Exploring its depth is not easy, it has been said that the Blue Hole is like swimming down a mineshaft. Only this mineshaft is inhabited by hammerhead sharks. Not for the faint of heart by any means, but if you’re a serious diver, the Blue Hole is a diving trip that should definitely be crossed off of your list.
As an established natural monument of Belize, since 1996, this cave forms part of the Lighthouse Reef Atoll. This area is rich in marine diversity, particularly endangered species, though the Blue Hole itself contains few marine life.
