This plane ride over the coastal waters of Belize is the only way to fully appreciate the Belize Blue Hole in all its glory. During your tour you will observe a dark circle of deep, dark blue water surrounded by reefs and a turquoise sea. Your tour will include several passes around this natural wonder.

The Belize Blue Hole is the largest known underwater sinkhole in the world, at 984 feet (300 m) across and 410 feet (125 m) deep. This sinkhole formed hundreds of thousands of years ago, and is characterized by stalactites, stalagmites, and a vast emptiness – not much marine life lives in this part of the ocean. Famed explorer Jacques Cousteau first popularized the amazing dives that the Blue Hole offers.

This sinkhole wears a necklace of coral called the Lighthouse Reef, which provides a habitat for healthy populations of marine life, including sharks. On the way to Belize Blue Hole you will pass over the Half-Moon Caye, which is named for its crescent shape. You’ll also see St. George’s Caye and the Turneffe Atoll. The water in this part of the Caribbean is so clear you can see the reefs from your plane.
