Explore the region's most unique natural treasure - a series of caverns connected by underground waterways! Begin with a ferry ride to the mainland where you will take a short van ride into the jungle to Rio Secreto Natural Reserve. Follow your guide into a subterranean world that had remained unexplored for millions of years. You'll marvel at the natural formations around every corner as you walk, wade, and swim through the caverns. Enjoy the crystal clear cenote framed by beautiful stalactites and stalagmites. After 1.5 hrs of exploring, enjoy a light lunch and beverage.
