Lighthouse Reef Atoll dive sites

Recreational dives at the Great Blue Hole typically descend to around 40 metres (130 feet) to reach the famous stalactite formations. The hole itself plunges to 124 metres, but divers stay within safe recreational or technical limits. Advanced Open Water certification is required.

The best conditions are from April to June, when seas are calm and visibility regularly exceeds 30 metres. The dry season (November to May) generally offers better conditions, though the site is diveable year-round. Hurricane season runs June through November.

The Great Blue Hole delivers a truly unique experience that few sites can match. Descending past the rim into the darkness and seeing ancient stalactites formed during the Ice Age is awe-inspiring. While marine life inside the hole itself is limited, the sharks circling the rim and the sheer geological spectacle make it a bucket-list dive.

Many experienced divers consider Half Moon Caye Wall the superior dive. While the Great Blue Hole is a unique geological experience, Half Moon Caye Wall offers far more marine life, healthier coral coverage, and longer bottom times. Most operators pair the two sites on a single day trip, giving you the best of both worlds.

The wall begins at just 10 metres and drops vertically into the deep blue. Pristine coral coverage includes massive barrel sponges, black coral trees, and enormous sea fans. Natural swim-throughs in the wall add adventure, and the remote location at Lighthouse Reef means the reef is exceptionally healthy and uncrowded.
