The most popular spot in Belize for scuba diving is Ambergris Caye. It is a small island whose main city, San Pedro, features streets that are covered by sand. Ambergris Caye provides access to amazing snorkeling and diving areas such as the Belize Barrier Reef, just half a mile off the east coast, which is the second largest coral reef system in the world. Divers can see both the barrier reef, which has its own distinct topography, as well as the walls offshore at the BlueHole. This 1000 foot circular coral reef that drops 400 feet into an incredible cavern filled with stalactites and awe-inspiring natural formations is truly a wonder to marvel.
