Discover the splendor of Río Secreto Nature Reserve: Journey to the heart of a cenote, and in the silence of the underground cave, marvel at the cathedrals of stalactites and stalagmites formed over millions of years. As you wade your way through clear turquoise water, an expert guide explains the geological secrets behind these limestone formations and points out local flora and fauna. Out of the caves and back in the jungle, enjoy a tasty buffet lunch featuring Mayan cuisine. Round-trip transport from Playa del Carmen hotels is available.
