Choose pickup at your Cancun hotel or meet directly at Rio Secreto Nature Preserve.
Arrive at Rio Secreto and listen as your guide reviews safety considerations and hands out equipment, including a hard hat with a lamp, a wetsuit, a life vest and water shoes.
Follow your guide into the underground cave to view the breathtaking crystal formations on both the ceiling and and the floor. Walk along a path through the caves and wade or swim through the river itself. Enjoy the sound of your group's movement through the subterranean cavern echoing off the walls. View the vibrant colors and dramatic mineral forms that lie hidden deep below the surface of the earth.
Exit the cave and opt for a shower at the Rio Secreto's facility. Swing in a hammock and relax in the Nature Preserve before boarding your bus for the return trip. End your Rio Secreto adventure with drop-off at your hotel in Cancun or at the Plaza Kukulkan.
