A wonderful day-trip destination from Cancun is the Si'an Ka'an Biosphere Reserve, a UNESCO World Natural Heritage Site just south of Tulum. Travel time from Cancun is approximately an hour and a half.
The Sian Ka'an Biosphere Reserve encompasses 1.3M acres on land and sea, including tropical forests, mangroves, savanna grasslands and coral reef, and is home to many conservation projects. Dozens of species are birds are found at Sian Ka'an, as are many types of land animals including jaguars and pumas. The reserve also has more than twenty archaeological sites, as the ancient Mayas had a thriving port in this area.
Most visitors experience Sian Ka'an on a guided tour. All-day tours are offered by CESiaK (the Centro Ecologico Sian Ka’an) and by Community Tours Sian Ka'an and other enterprises.
