The Belize Barrier Reef is the southern portion of the Mesoamerican Barrier Reef, the longest reef system in the Western Hemisphere. The Belizean section extends 186 miles north to south, and protects Belize's Caribbean Coast from high waves.
The reef is largely submerged, but numerous cayes and atolls break the surface. A caye (pronounced "key") is a low-elevation island formed on the surface of a coral reef. Belize has dozens of cayes besides Ambergris Caye—the country's largest and most famous. An atoll is a coral island encircling a lagoon. Belize has three major atolls: the Turneffe, Lighthouse Reef, and Glover's Reef atolls.
Caye Caulker, 20 miles northeast of Belize City and 10 miles south of Ambergris, is a narrow island ringed with mangroves and a thin strip of gleaming sand. Caye Caulker's only town, located on the southern half of the island, offers basic accommodation and diving tours. Near the island, you can dive among shipwrecks, sponge gardens and coral caves. Day tips are also available to the Lighthouse Reef (site of the Great Blue Hole) and Turneffe atolls. Flights between Caye Caulker and both Belize City and Ambergris are available.
Turneffe is the largest of the Belize's three atolls. Divers are drawn here by steep walls, numerous caves and the wreck of the Sayonara. Sportfishing is an added attraction, with flats fishing for permit, tarpon, snook and bonefish.
Twelve miles east of Turneffe and 62 miles from Belize City is the Lighthouse Reef Atoll, one of the world's top dive sites. The atoll contains approximately fifty miles of wall and reef diving, with crystal clear visibility. The Great Blue Hole, near the center of the atoll, is a collapsed limestone cave nearly 1,000 feet across and 410 feet deep. Here you can dive with giant groupers and several species of shark.
Half Moon Caye National Monument, at the southeast end of Lighthouse Reef Atoll, is a spectacular wall dive site. The caye is also a nesting ground for the Red-footed Booby (Sula sula) and the Magnificent Frigatebird (Fregata magnificens). Hawksbill (Eretmochelys imbricata) and Loggerhead turtles (Caretta caretta) lay their eggs on the cay's beaches.
Glover's Reef Atoll, 45 miles west of the mainland, is the most remote Belizean atoll. It is also a national marine reserve and a UNESCO World Heritage Site. The atoll's central lagoon is famous for its wall dive sites—nearly fifty miles of them ranging in depth from 25 to 2,700 feet. The atoll's 700 patch reefs offer snorkelers the chance to swim among coral gardens with sea turtles.
Located 11 miles east of Placencia, Laughing Bird Caye National Park takes its name from the Laughing Gulls (Larus artricilla) that used to nest here. The caye is part of an elongated ridge of reef known as a faro ("fah-ro") or shelf atoll. The west or lagoonside of Laughing Bird Faro contains colonies of lettuce, boulder star and fire coral; sponges; and sea stars. Here you can dive or snorkel with angel fish, bottle nosed dolphins and trumpet fish.
Just north of Laughing Bird, the enormous South Water Caye Marine Reserve protects numerous cayes (e.g. Carrie Bow, Man-O-War, Tobacco, and Wee Wee), sea grass beds, shallow coral reefs, and vertical walls. Sea turtles and eagle rays are common here. Harlequin bass, barracuda, moray eels and dolphins can also be observed here.
Mosaico Travel Services arranges full or multi-day dive trips to each of these sites. Many of the cayes offer basic lodging. Live-aboard dive charters are also available. Speak with a Mosaico travel planner today at 801.582.2100. We’ll take care of the details.
