Plan on visiting the large Mayan Ruins at Tulum and Coba. Plan some time to hit one or both of these spectacular sites. A smaller site, but in many ways as interesting is Muyil, which is about 20 minutes south of Tulum. From Xcalak, heading to Chetumal about 2 1/2 hours you will come to the Ruta Maya, and Kohunlich, Kinichna, and Dzibanche.
