Cancun is more than a party destination with luxury hotels and villas. It is the Yucatán Peninsula’s gateway to a world of jungle-clad Mayan pyramids, the crystal caves of Rio Secreto, and a scuba paradise off Isla Mujeres. Days can be spent lounging next to Caribbean waters with margarita in hand, or exploring the nearby jungles and cenotes. Make time to visit Chichen Itza or the Tulum ruins—both places you can go for guided morning explorations before the grounds open to the general public. For something different in Mexico’s most popular beach destination, spend an afternoon in a downtown plaza, or venture out for dinner and a Cirque du Soleil show in the heart of Riveria Maya.
