Mexico Coast-to-Coast: Puerto Vallarta to the Mayan Riviera

Go coast-to-coast from the Pacific to the Mayan Riviera on this three-week adventure across Mexico that features tons of highlights along the way. You’ll stroll (or dance) past mariachis in Guadalajara, wander the narrow streets and tunnels of Guanajuato, and visit ancient sites like the Aztec capital of Teotihuacán, jungle-clad Palenque, and the massive pyramid at Chichen Itzá, just to name a few. All that adventure is sure to work up an appetite — thankfully Mexico City’s famous street tacos and Oaxaca’s many types of mole will more than hit the spot. Hotels (21 nts).
