AARP's Guide to Cancún
Cancún is one place where postcards don’t oversell what you’ll see with your own eyes: Reflections of fluffy white clouds scud over luminous aquamarine waters along fine white-sand beaches. And while it was purpose-built for tourism in 1974, the resort area can serve as a launching pad for forays into Mexican culture and Mayan heritage. You’ll find all that, plus gorgeous oceanside vistas, if you head south along the gorgeous Riviera Maya, where the towns of Puerto Morelos, Playa del Carmen, Akumal and Tulum line the 86-mile coastline.
