Floating through Mexico's underground rivers
The park's signature activity: snorkeling and floating along thousands of meters of natural cave waterways, fed by cenotes and limestone filtration.
The underground river circuit is the heart of any Xcaret visit. You enter at one of three entry points, pick up a flotation vest and a snorkel mask, and drift through roughly 600 meters of cave passages before exiting into a sunlit lagoon. The water is cool, clear, and unusually still — there are no rapids, no currents, and the route is roped off for safety.
Total swimming distance exceeds a kilometer if you link the two branches. Most first-time visitors take one branch (about 45 minutes) and come back another year to do the other. If you are not a confident swimmer, ask for a life vest at the entrance — every visitor gets one free.
