AAA Editor Notes
Calakmul ruins are a good 2-hour drive w. of Chicanná; from the Mex. 186 turn-off (watch for signs), a winding road heads s. about 60 km (37 mi.) into the Calakmul Biosphere Reserve. This huge archeological zone—a UNESCO World Heritage Site—sits in the state of Campeche near the Guatemala border. A Classic-era superpower that often battled nearby Tikal, Calakmul is one of the largest Mayan cities ever discovered and boasts the tallest Mayan pyramid (180 feet) in Mexico.
