The Blue Hole of Belize is one of those places anyone would love to travel to during their lifetime, especially those interested in scuba diving. This sinkhole is the deepest part off the Belize reef AND it's shaped as a perfect circle! It was a cave above land level until the last ice age when it was flooded and the roof collapsed. The dive is deep enough to give you that drunk feeling (Nitrogen Narcosis) at the 40 meter mark while staring at a sea of sharks. In total its about 120 meters deep and 330 meters in width. Many divers have been left blown away after traveling here.
