Sian Kaán

The Sian Ka’an Biosphere Reserve

This is a paradise full of natural wealth, an unspoilt area located on the Caribbean coast of the State of Quintana Roo in Mexico. It was declared a World Heritage Site by Unesco in 1987. It has the largest water tables in Mexico and the most extensive underground river system on earth which has its source in the vast Mayan jungle and allows the existence of the second largest barrier reef in the world.

Sian Ka'an covers an area of 528,147 hectares, which belong to the Quintana Roo municipalities of Felipe Carrillo Puerto and Tulum.

You can find wide, white sand beaches and small bays and mangroves on the coast of this Biosphere Reserve, and its diversity of vegetable and animal biological species make it unique (103 mammal species such as the jaguar, puma, ocelot, margay, juguarundí, saraguato monkey; reptiles and 345 species of birds).

The climate is warm and sub-humid and the rainy season is in the summer.


The region contains 23 archaeological zones, the oldest dating back around 2,300 years. It is thought that the zone was inhabited by the Maya during the Pre-classic and Classic periods, and it is presumed that an ancient trading route was located in the far north which connected the ancient cities of Tulum and Muyil, crossing through the lagoons and mangroves.

Sian Ka'an introduces visitors to one of the most exciting and richly diverse places in the Riviera Maya.
