Lighthouse Reef sits far offshore and contains some of Belize’s most famous diving. Its walls, coral ridges, grooves, channels and swim-throughs create far more variety than the atoll’s best-known attraction alone might suggest.

The Great Blue Hole draws many divers to Lighthouse Reef, but the surrounding walls are often the dives they remember most. Half Moon Caye combines garden eels and a beautiful wall with the chance of turtles, eagle rays and Caribbean reef sharks, while other sites around the atoll offer colourful sponges, healthy coral and clear blue water.

Lighthouse Reef is about 50 miles from Belize City, so reaching it by day boat requires an early start and a long crossing in both directions. A liveaboard remains within the atoll, allowing you to arrive at sites before or after the main day-boat traffic, complete several dives and explore more than the headline locations. Staying overnight also makes sunset and night dives possible at suitable reefs, when tarpon, octopus and lobsters become more active.

The diving ranges from approachable upper reefs to deep walls where buoyancy and depth awareness are essential. Currents vary around the atoll, and the captain or dive guide will choose sites according to weather, sea conditions and the experience of the group.

Lighthouse Reef is included within the Belize Barrier Reef Reserve System, and protected-area rules apply at specific locations. Weather can still affect access, particularly to the Blue Hole.
