The most sought after dive destination in Belize! The Great Blue Hole is a giant underwater cavern 70 km (43 mi) off the coast of Belize. The hole is circular in shape, over 300 m (984 ft) across and 108 m (354 ft) deep, and was formed when sea levels were much lower thousands of years ago.
As ocean levels began to rise, the cave was flooded. The Great Blue Hole is a part of the Lighthouse Reef and larger Belize Barrier Reef Reserve System, and was made famous by Jacques Cousteau, who declared it one of the top ten scuba diving sites in the world.
Today the Great Blue Hole is an UNESCO World Heritage Site and remains one of the top dive sites in the world. St. George’s offers a full-day dive trip to the Blue Hole for experienced and advanced divers. To fully appreciate the wonders of this incredible site, we descend to a depth of more than 100 feet and therefore divers are required to have their Advanced Open Water certification.
