With water temperatures remaining warm year-round and the protected nature of the reef, it’s possible to find a fantastic diving experience at any time of the year. Home to three different Atolls, myriad cayes and many types of coral reef habitats, the diving found in this tiny jewel of a country is not to be missed. Most sites have little-to-no current making them great for beginners. More advanced sites, like the Great Blue Hole, will take you to depths of 130 feet. Visibility is regularly upwards of 60-100 feet, giving you a great view of all the marine life to be found on the reef. We’ve rounded up the best dive sites in Belize for you, organized by location.

Glover’s Reef Atoll
Glover’s Reef is one of the least-visited sites due to its remote location. The trek to Glover’s Reef is definitely worth it for the rich and healthy reef systems that you encounter there.

Turneffe Atoll Dive Sites
Turneffe Atoll is the largest of Belize’s atolls, being 30 miles long and 10 miles wide. It is also the closest atoll to the mainland, though the boat ride is still about 2.5 hours. Conditions permitting, three dive sites will be chosen by the divemaster to round out a day trip to Turneffe Atoll.
