Sian Ka'an Biosphere Reserve

The Sian Ka'an Biosphere Reserve, one of Mexico's largest parks, covers more than 1 million acres of coastal jungle or about 20 percent of the state of Quintana Roo's land. This virgin wilderness is home and sanctuary to innumerable species of tropical flora and fauna, of which, the jaguar found here is counted as one of the many protected species.

As eventful and exhilarating as the encounters with the native wildlife are, archaeologically, more than two dozen ancient Mayan sites have been discovered here in various states of ruin. Evidence of habitation dates back at least 2,000 years but most sites uncovered belong to the post-Classic Period, around 1200 AD.
