The Belize’s coastline comprises the Belize Barrier Reef, covering more than three-quarters of the Mesoamerican Barrier Reef System, the second largest reef in the world after Australia’s Great Barrier Reef.
The Belize Barrier Reef, Belize’s 3 offshore atolls, several hundred sand Cayes, mangrove forests, and coastal lagoons are part of the Belize Barrier Reef Reserve System that is a UNESCO World Heritage Site. This makes Belize a major diving destination, visited by thousands of scuba divers every year. The Belize Barrier Reef extends from northern Ambergris Caye to the Sapodilla Cayes in Belize’s southernmost regions. Apart from great divespots it is also prefect for snorkeling. Most of the cayes are uninhabited. The most famous, developed ones areAmbergris Caye and Caye Caulker.
Belize’s biggest attraction is its Atolls; ring-shaped coral reefs with a coral rim encircling a (shallow) lagoon. These Atolls are Turneffe Island, Lighthouse Reef, and Glover’s Reef. Belize’s most famous divespot is The Great Blue Hole, situated in the Lighthouse Reef System. It lies approximately 100 km (60 miles) off the mainland and for many this is one of the most amazing dive sites in the world. The Great Blue Hole (or in short, The Blue Hole), is an almost perfectly circular hole of 145m/480 feet deep and it is the depth of the water that gives the deep blue color that causes such structures throughout the world to be known as “blue holes.”
Apart from these Atolls, Belize offers many other divespots for all type of divers and for all experience levels. Like most Caribbean destination the water is warm and crystal clear with great visibility. In Belize this visibility is even greater because of the fact that the reef is roughly about 13-25km (8-16 miles) from the shore so that it is not impacted by rain washing off the land or mud from the rivers. The water temperature is pleasant year round averaging 26°C (mid to high 70’s F).
