The Belize Barrier Reef is a series of coral reefs. It goes along the coast of Belize, about offshore in the north and in the south. The Belize Barrier Reef is a long section of the long Mesoamerican Barrier Reef System. The reef system runs continuous from Cancún on the northeast tip of the Yucatán Peninsula through the Riviera Maya down to Honduras. This makes it one of the largest coral reef systems in the world after the Great Barrier Reef in Australia and the New Caledonia Barrier Reef.
