Visit the unique ecosystem of Sian Ka'an, a UNESCO World Heritage site, during this tour from Tulum. With an expert local guide, first stop by the Mayan archaeological site of Muyil, located just a short walk into the pristine jungle. At Sian Ka'an, take a boat ride through the mangrove forests that line the lagoon and the canals, ending up at Xlapak. Jump in with a life vest and as you float down the canals, keep an eye out for the more than 300 species of birds as well as other native flora and fauna. Meet your boat captain at the exit point and return to your Tulum hotel, snacking on provided chips and beverages on the way.
