Isla Contoy is a small, protected island north of Isla Mujeres, managed as a national park dedicated to seabird conservation. Visitor numbers are strictly limited each day, there is no lodging, and access is only through authorized tour operators. The result is one of the least disturbed stretches of coast in the Mexican Caribbean.
Tours land at a modest pier near the beach, where visitors can swim and relax in clear water. A small nature museum explains the island's ecology, and short trails, sometimes with an observation tower, allow bird watching across the lagoons. Brown pelicans, frigatebirds, cormorants and ospreys are among the species that nest or roost here in large numbers. Mangroves and dunes create important habitat, and sea turtles use the island's beaches for nesting. Most trips include a snorkeling stop at a reef along the way, often Ixlache, before arriving. The boat ride itself, through open water with possible dolphin sightings, is part of the appeal.
Contoy suits nature lovers and families looking for a calm, educational day out. Visitors must follow park rules, including staying on paths and limiting time ashore. Many tours return via Isla Mujeres, sometimes stopping in the town, and Hacienda Mundaca, a historic estate on Isla Mujeres, makes a related stop.

The small landing beach on the island's western, lagoon side, with white sand, palms and calm clear water where visitors swim and relax after the boat ride. Only a limited number of people are allowed on the island each day. Bring reef-safe sunscreen and pack out any trash you bring.
The long exposed beaches on the island's eastern, open-sea side, where loggerhead, green and hawksbill turtles come ashore to nest in summer. Most of this coast is closed to visitors to protect the nests. Stay on marked paths and follow the rangers' guidance during your visit.
A small museum and visitor center near the dock, with displays on the island's birds, reefs, turtles and conservation history, including skeletons and specimens of local marine life. It explains why the island is a protected national park. Look through it before walking the trails.
Short sandy trails lead from the dock through coastal scrub, past lagoons and dunes, with signs about the plants and wildlife of the island. Iguanas, hermit crabs and many birds are seen along the way. The walk is easy; wear a hat and repellent, as there is little shade.
A tall lookout tower near the visitor center giving views over the narrow island, its lagoons, mangroves and the turquoise sea on both sides. The climb is by stairs. It is the best way to see the shape of the island, and binoculars help to spot birds nesting in the trees below.
Isla Contoy is one of the most important seabird refuges in the Mexican Caribbean, with nesting colonies of brown pelicans, magnificent frigatebirds and double-crested cormorants, plus ospreys and herons. Boats pass the colonies slowly on the way in. Bring binoculars and keep your voice low near nests.
Inside the island, mangrove lagoons and coastal dunes form the habitats that support its birds, fish nurseries and crabs. Walkways and viewpoints let visitors see them without disturbing the area. Stay on the paths, as dunes erode easily, and look for juvenile fish in the clear lagoon water.
A shallow reef near Isla Contoy where boat tours stop for snorkeling among coral heads, sea fans and schools of reef fish, sometimes with rays and turtles. It is usually visited on the way to the island. Wear a life vest if you are not confident, and avoid touching or standing on the coral.
Licensed tour boats from Cancún and Isla Mujeres take about an hour to reach Isla Contoy, often with dolphins, flying fish and seabirds along the way, and include lunch on the island. Only authorized operators may land. Book ahead, as daily visitor numbers are capped, and bring seasickness tablets.
