I recently had the opportunity to visit Belize on a dive trip in the vicinity of Turneffe Caye, Half Moon Caye, and Long Caye. This included a dive down into the giant marine sinkhole knowns as the Great Blue Hole. The site was made famous by Jacques Cousteau, who, in 1971, declared it one of the top five scuba diving sites in the world. In 2012, Discovery Channel ranked the Great Blue Hole as number one on its list of "The 10 Most Amazing Places on Earth".
