Water- and tear-proof, this sturdy, full-color map shows cities, roads, Maya sites and attractions south to Campeche and the Sian Ka'an Reserve. With photographs and site diagrams of Chichen Itza, Uxmal, Tulum, Coba and other sites and inset maps of Cancun and Merida at a scale of 1:500,000, it has the detail and information you need. Those heading south to Chetumal and Belize will want a map of the entire Yucatan Peninsula instead or in addition.  (MEX248, $11.95)
