Diving Belize's Great Blue Hole

Belize Blue Hole Diving Tours

Touted as one of Jacques Cousteau’s favorite dive sites, the Great Blue Hole National Monument at Lighthouse Reef Atoll is the world’s largest oceanic blue hole. Divers who descend into the tranquil abyss will marvel at the tropical marine life and geologic wonders such as giant stalactites. The Great Blue Hole is also available as a snorkeling tour.


Great Blue Hole Diving

Blue Hole trips are full-day excursions to Lighthouse Reef Atoll, which is approximately 50 miles by boat from Isla Marisol Resort.  The first dive at the Great Blue Hole is a maximum depth of 130 feet.  During the surface interval, participants are brought to Half Moon Caye for lunch.  The second dive is at Half Moon Caye Wall.  For those not up for a second dive or snorkel, there is the option of exploring the island and its nesting colony of Red Footed Booby Birds.  Half Moon Caye was designated a bird sanctuary in 1928, making it Belize’s oldest site for wildlife protection.

The Blue Hole Excursion is two dives suitable for intermediate and experienced divers.  A local check-out dive at Isla Marisol is required before participating in the Blue Hole Dive.  Snorkelers of all ages and abilities are welcome.  A minimum of 6 participants are required to make the trip to Lighthouse Reef Atoll, which is approximately 2 hours away.
