The Great Blue Hole is a world-class destination for recreational scuba divers attracted by the opportunity to dive in crystal-clear waters and see myriad species of marine life including tropical fish and spectacular coral formations.
The marine life in these areas includes nurse sharks, giant groupers, and several types of reef sharks such as the Caribbean reef shark and the Blacktip shark (Carcharhinus limbatus). Dive excursions to the Great Blue Hole are full-day trips, that usually consist of one dive in the Blue Hole and two additional dives in nearby reefs.
The Belize Blue Hole is located approximately 100 kilometers (62 miles) offshore of Belize City. The perimeter of the Blue Hole is Lighthouse Reef, a natural coral atoll.
Size and Dimensions
The Belize Blue Hole is almost perfectly circular in shape, measuring 300 meters (984 feet) across and 108 meters (354 feet) deep.
The Belize Blue Hole is the largest sea hole in the world. Sea holes refer to caves that were submerged when rising waters covered them. Most sea holes, just like the Belize Blue Hole, were submerged at the end of the last great Ice Age some 10,000 years ago.
How was it named?
The actual name of “The Great Blue Hole” was created by British diver and author Ned Middleton after having lived in Belize for 6 months. He was so impressed with this natural feature that he reasoned in his book “Ten Years Underwater” that if Australia could have ‘The Great Barrier Reef’ then Belize could equally have ‘The Great Blue Hole’ — thus setting this feature apart from similar, albeit lesser in size, structures.
Accidents and presence of Monster in Blue Hole
Despite the beauty it offers, the Great Blue Hole of Belize also often witnesses accidents including the death of divers. According to reports, several divers have so far lost their lives in the darkness of the Blue Hole for various reasons. Even though there are no currents in the Blue Hole, accounts suggest the death occurs due to nitrogen narcosis as they go deeper. When divers cross 135ft or more, according to reports, they start feeling numbing sensation or euphoria, eventually causing death.
