Just off the coast of Belize there is an underwater sinkhole that many researchers believe is the largest of its kind. It gets its name “The Great Blue Hole” because it looks just like that- a circular hole in the ocean that is characterized by its rich blue color. The Great Blue Hole is over 300 meters (984 ft) across and 125 meters (410 ft) deep.
During a time where sea levels were much lower, the Great Blue Hole was originally a limestone cave. However, as the levels began to rise the cave flooded and collapsed. This makes it a popular site among divers, who come from all over to see this truly magical feat of nature.
Jacques Cousteau was one of these divers who made the location very popular back in 1971. He was able to investigate and explore the area and confirm how it was formed. There are even stalactites and stalagmites that can be seen below the surface. The Great Blue Hole is part of the Belize Barrier Reef Reserve System.
While you are in the area you will most likely be greeted by some of the local fish species. These can include the Midnight Parrotfish, the Caribbean Reef Shark, among others. There are also many sharks like the bull sharks and hammerhead sharks, but they are not sighted as regularly as the fish.
Generally to get to the Great Blue Hole you would need to a take a day trip from one of the many coastal tourist communities in Belize. The next time you visit Belize, this is a trip that you should consider taking.
