The Great Blue Hole and Lighthouse Atoll

Belize Diving Services offers a fabulous, full day of diving to The Great Blue Hole and Lighthouse Atoll. This three-tank dive tour is one of the best diving experiences in the Caribbean and the entire world.


Diving the Great Blue Hole in Belize is a bucket list item for many SCUBA divers. The Great Blue Hole is the first dive of the day. This remarkable sinkhole measuring over 300 metres (984 ft.) across and 125 metres (400 ft.) deep. The Great Blue Hole is a Belize National Monument and UNESCO World Heritage site. Experienced divers can venture to the limits of recreational SCUBA diving to see Costeau’s giant stalactites at 40 metres (130 ft.). This profile is for experienced divers only—divers with 25 or more dives. For those not qualified for this depth or who simply want a longer dive profile, Belize Diving Services offers a second dive profile to 24 metres (80 ft.). On this dive, you will not swim through the stalactites, however, you will experience the drop-off and likely see some sharks.

After the Great Blue Hole dive, it’s a 25-minute boat ride to Half Moon Caye Wall for the second dive of the day. Along walls that drop beyond 300 metres (1,000 ft.), you’ll see colorful sea fans, giant barrel sponges, turtles, eagle rays, eels, octopi, reef sharks and sting rays hiding in the sand flats. Half Moon Caye is a picturesque Caribbean island with a bird sanctuary observation deck that overlooks a Red-Footed Booby Colony. We have lunch on the Caye and explore the island a bit.

The third and final dive of the day, Long Caye Aquarium, is a beautiful destination where marine life is healthy and plentiful.

These three sensational diving sites are located on Lighthouse Atoll, 50 miles southeast of Caye Caulker. This is a full day of diving and boating (two hours one way) that starts with a very early wake-up call, but it is a once-in-a-lifetime experience. The Great Blue Hole is the check-off item, but most divers say Half Moon Caye and Long Caye Aquarium are the highlights of the day—and that’s what they talk about on the boat ride home!

Breakfast and lunch are included in this tour, prepared under the supervision of owner and chef Dani Petersen.
