Great Blue Hole
Iconic offshore sinkhole dive with giant stalactites.
Local operator required
Practical access is by organized day boat or liveaboard to Lighthouse Reef, and operators often screen divers for deep-dive readiness before confirming the Blue Hole profile.
About Great Blue Hole
The Great Blue Hole is Belize's iconic offshore sinkhole dive at Lighthouse Reef, where a ring of coral frames a vertical cobalt drop and the main attraction is descending past limestone walls to giant stalactites in dark blue water. Most trips pair the sinkhole with brighter nearby reef or wall dives, so the draw is geology, blue-water atmosphere, and the sense of place more than dense coral cover or nonstop fish action.

Where Is Great Blue Hole?
Great Blue Hole Planning Details
Depth range, seasonality, and planning context.
Reported Depth
0m - 40m
Depth Note
The monument is far deeper overall, but recreational dives usually start shallow on the rim and descend to roughly 40 m / 131 ft for the stalactite profile.
Best Season
April to June usually offers the calmest seas and strongest visibility for Great Blue Hole trips, although Lighthouse Reef runs remain weather dependent year-round.
Typical Conditions
Expect very clear blue water, low light on the deep descent, and full offshore exposure during the boat run. The interior often feels calmer than the surrounding reef edge.
Safety & Access At Great Blue Hole
Hazards, restrictions, and access requirements.
Safety Notes
This is an offshore deep-dive outing best kept within training and gas-planning limits. Operators commonly expect experienced divers because the signature descent is dark at depth, remote, and weather dependent.
Access Restrictions
Boat access only. Trips run weather permitting, and operators commonly require advanced or otherwise suitable deep-dive experience for the scuba profile.
Legal Notes
The Great Blue Hole sits inside the Blue Hole Natural Monument within the Belize Barrier Reef Reserve System. Expect protected-area rules and marine reserve or park fees on organized trips.
Local Intel For Great Blue Hole
Community notes to help plan your visit.
Scuba
The signature scuba dive is a deep wall descent to the stalactite zone, usually combined with shallower reef or wall dives elsewhere on the same full-day trip. Operators treat it as an experienced-diver outing because of the offshore logistics and dark deep section.
Snorkel
Non-divers can usually join as snorkelers on full-day boats, with practical snorkeling limited to the shallow coral rim or the paired reef stops rather than the sinkhole descent itself.
