The Great Blue Hole, Belize
‘Great’ doesn’t quite do this justice given its immense scale, a vast marine sinkhole that measures more than 300 metres from side to side and plunges deep down into the darkest reaches of the ocean, more than 125 metres from top to bottom, with mysteries galore to be explored and discovered in its depths.
Ever popular with divers and underwater adventurers, this is no place for the faint of heart, being riddled with caves and caverns, with haunting stalactites and stalagmites, and creatures ‘ their number including sharks ‘ lurking in every corner.
Located in the centre of Lighthouse Reef, a spectacular atoll that lies some 43 miles off the coast of Belize, The Great Blue Hole has long called to those keen to uncover its secrets. But as explorers galore have discovered, once beneath the surface, descending into the hole is not something to undertake lightly.
