Forty minutes outside Chetumal, at the edge of the Kohunlich ceremonial grounds, this ecological luxury resort lets you feel adventurous without really roughing it. Daily excursions include trips to nearby ruins, lagoons, and forests for bird watching, mountain biking, kayaking, rappelling, and hiking; the most popular option is a night kayaking tour that concludes with a four-course dinner on the shores illuminated by tiki torches. You return in the evening to Mexican-style
suites filled with natural textiles and woods. All guest quarters are strung along a serpentine jungle path; they're very private and have showers opening onto small gardens. Most guests stay a week to take advantage of all the tours, the infinity pool, and spa. Plan to disconnect since there are no TVs or Internet here.
