About

Tour Overview

Enjoy a fantastic experience in one of the most incredible locations in the Riviera Maya that begins at the moment you arrive at the Natural Reserve where you will be greeted by our highly trained guides and equipped like a professional dive master. You will put on a wetsuit, helmet with a special lamp and wet shoes.

At Rio Secreto (Secret River), you will experience the silence of a world below, crossing for an hour and a half through the crystalline water museum. Filled with a kaleidoscope of speleothems, walk an easy 600 meter route amidst the thousands of stalactites and stalagmites found in this protected natural reserve. This is an underground adventure like no other!

After the tour, you will be provided with an excellent lunch of light foods and have a chance to relax at this great natural habitat.

Frequently Asked Questions

The water is cool, with a temperature of 22º C to 24º C, or 69º F to 75º F. However, our visitors wear neoprene wetsuits and life vests.

  • In order to protect the safety of individuals, the group and the cave, you are not allowed to bring photography or video equipment into the caves, since you can slip or damage a natural structure while inside. However, you may use them outside the cave.
  • During the expedition, there is professional photographic equipment and lighting inside the cave, which allows to safely capture your adventure on film and deliver high quality photographs. Common cameras are barely able to generate a bright enough flash inside Rio Secreto and they are unable to capture and illuminate the beauty and scope of the entire cave. You can purchase these photos individually or in CDs.
