The reefs of Xcalak are part of a much wider, inter-connected eco-system that includes lagoons, bays, rivers, estuaries, and the largest wetlands in Mexico.

Chetumal bay, behind Xcalak, is home to one of the largest populations of manatees living in the wild. Often, due to reasons not yet fully determined, these manatees go out to the ocean and swim amongst the reef. These encounters with wild manatees on pristine reefs and crystal-clear waters are truly spectacular.
