History of the Great Blue Hole in Belize

Belize’s Great Blue Hole is a natural creation that has intrigued scientists and marine enthusiasts for centuries. It is believed that the hole was formed during the ice age through a series of glacial events. Further, incidents of erosion of rock and deposition of material in the area, are believed to have created the wonder that is called the Great Blue Hole.

Where is the Great Blue Hole?

The cavern is located just about 60 miles off the Belize coast and is near the center of the Lighthouse Reef atoll. It is part of the Barrier Reef Reserve System and was designated a world heritage site of the United Nations Educational, Scientific and Culture Organisation (UNESCO) in 1996.

The aerial view of the hole shows an almost perfectly circular dark blue abyss surrounded by coral and gorgeous turquoise waters. The contrast of dark blue and turquoise is an eerily stunning sight that beckons visitors and teases about the true depth of the hole.

However, this view does not prepare you for the unique positioning of stalactites and stalagmites and other limestone formations which are accessible only by a diving session. The area, a popular tourist spot, is one of the must-see diving locations on a trip to Belize.

The total diameter of this phenomenon measures 1,000 feet and creates a natural home for marine life.
