Fodor's Expert Review Chankanaab Beach Adventure Park

Chankanaab, translated as "small sea," consists of a saltwater lagoon, an archaeological park, and a botanical garden, with reproductions of a Maya village and Olmec, Toltec, Aztec, and Maya stone carvings scattered throughout. You can swim at the beach, and there's plenty for snorkelers and divers to see beneath the surface, including underwater caverns, a sunken ship, crusty old cannons and anchors, a sculpture of the Virgen del Mar (Virgin of the Sea), and parrot fish and sergeant majors galore. Note, though, that to preserve the ecosystem, rules forbid touching the reef or feeding the fish. A seal show is included in the admission, and you'll find dive shops, restaurants, gift shops, a snack stand, and dressing rooms with lockers and showers right on the sand. Chankanaab also has a Dolphin Discovery facility where you can swim with the much-loved marine mammals.
