Sian Ka'an Biosphere Reserve

Tulum, Quintana Roo, Mexico

The Basics

The area’s ecological diversity is the biggest draw to vast Sian Ka’an, which, at 1 million acres (404,686 hectares), is the largest protected area on the Mexican Caribbean. Ride a boat through the lagoons of Boca Paila and Caapechen for opportunities to spot animals like spider monkeys, crocodiles, flamingos, ocelots, and pumas in their natural habitat along the shore. Or take a snorkeling tour on the world’s second-largest barrier reef, home to more than 500 species of fish as well as dolphins and marine turtles. Other popular activities include kayak tours, paddleboarding, fly fishing, and visits to Maya archaeological sites including the El Castillo temple and the ancient trading post of Muyil, located among the mangrove forests. Guided tours and private tours help you see more of the reserve’s attractions in a limited amount of time.
