Playa del Carmen

- Now the third-largest city in Quintana Roo

-Ranks up there with Tulum as the Riviera's trendiest cities. The town is ideally located: close to Cancún’s international airport, but far enough south to allow easy access to Cozumel, Tulum, Cobá and other worthy destinations. The reefs here are excellent, and offer diving and snorkeling close by. With daily cruise-ship visitors, Playa's tourist center now feels like a mass-tourism destination, but it manages to retain its European chic, and one need just head several blocks west of the main strip to catch glimpses of the nontouristic side of things.
