Mexico's Sian Ka'an Biosphere Reserve is known as one of the great biodiversity hotspots of the world and has been a World Heritage Site since 1987. It is a stunning reserve where ancient history, biodiversity, and cenotes come together. Visiting Sian Ka'an is one of the great, less touristy things one can do while visiting Tulum.

See scores of tropical birds as well as exotic butterflies, native orchids, and much more. On a lucky day, the tour may even be able to spot a manatee or two swimming up to the surface for air. Mexico's Yucatán Peninsula is so much more than just beaches and cenotes - it is one of the most bio-diverse regions in the world.
