Stretching from the fishing village of Puerto Morelos to the biosphere reserve of Sian Ka'an, the Mayan Riviera offers an unforgettable Caribbean coastline experience. Divers and snorkelers will be dazzled by the wrecks and marine life of Xcaret and the Puerto Morelos reef. Use a zip line to descend into the sacred subterranean caverns of LabnaHa Cenotes & Eco Park, where you can snorkel an underground river under a canopy of stalactites.
