Located approximately 60 miles off the mainland of Belize, the Great Belize Blue Hole is a large underwater sinkhole near the center of Lighthouse Reef. The Blue Hole measures about 900 feet in diameter, making it the largest formation of its kind in the world. The Great Belize Blue Hole (which forms part of the UNESCO World Heritage Barrier Reef Reserve System) is more than 400 feet deep and is arguably one of the best scuba diving destinations in the region.

Divers can expect to see some really unique underwater landscapes and a huge variety of marine life, including many species of shark, giant groupers, and much more.

Day trips usually include one dive in the Blue Hole and two other reef dives.
