Playa del Carmen is just remote enough that the beach – really the only one there is – doesn't have a proper name. Still, it's the highlight of most vacationers' time in the area, and makes for a delightful way to spend your afternoons.
Often lauded as one of the best-kept secrets on the Yucatan Peninsula, Rio Secreto (or Secret River) is an underground river and collection of caves. The bright turquoise water contrasts with the caramel- and mocha-colored rock formations within the caves, which include stalactites and stalagmites. Visitors can swim in the river, climb through the caves and enjoy the natural beauty of the area.
Both experts and travelers say that Xcaret is a sort of Yucatán-style Disneyland, a large outdoor "eco-park" filled with an aviary, a dolphin aquarium, a turtle sanctuary and a beach perfect for swimming, diving or snorkeling.
