Arrecifes de Cozumel National Park

Cozumel, Quintana Roo, Mexico

The Mesoamerican Barrier Reef System is the second-largest coral reef in the world and runs along the coasts of Belize, Guatemala, Honduras and Mexico, stretching more than 1,000 kilometers (600-plus miles). The various corals are an underwater habitat for fish, turtles and sharks, and it’s little wonder that the reef draws divers from around the world to explore its depths. Snorkelers also find the reef a satisfying spot to seek and spy brittle stars and starfish, sea whips and sponges and numerous species of colorful fish.
