A Nature Reserve that'll take your breath away

The discovery of Río Secreto, previously known as Pool Tunich, has brought much excitement to Quintana Roo. This system of caves, formed over centuries by an underground river, is located only a few miles from Playa del Carmen. It is by far the longest partially flooded cave in the Yucatan Peninsula, but what makes Río Secreto even more special is the fact that it is semi-sunken. Most caves found in the Yucatan are underwater, and if you want to explore them, you must receive specialized training in cave diving. That requires lots of practice and study, as well as a hefty investment in diver certification and dive gear. Río Secreto has more than 12 kilometers (7.5 miles) of semi-sunken cave mapped out with 15 natural outlets located in different areas. There’s nothing else like it!

Imagine finding a hole in the ground and lowering yourself into the unknown where you uncover a breathtaking underground world untouched for thousands of years. That is truly how this underground river system was first discovered. Before 2007, almost no one had entered Río Secreto except for the man who first found it. Since then, Río Secreto has become a protected nature reserve where you can safely explore the Yucatan Peninsula’s most awe-inspiring underground universe.

Keep in mind, this exotic and fragile geological formation requires an incredible amount of eco-awareness and sensitivity. We limit the size of tour groups to minimize impact on the cave. This will ensure that many generations get to see our planet’s natural history carved in mineral substances.

A journey through Río Secreto is surreal, mystical and memorable. Whether you’re an adventurer, world traveler, or simply a curious soul, we welcome you to experience one of the most intriguing natural attractions in the Riviera Maya.

Río Secreto has evolved and reached maturity, both as a brand and as a Natural Reserve, by adding on to its great adventure with Rio Secreto Plus, the most spectacular tour in the Mexican Caribbean.

This tour includes the traditional Rio Secreto experience that offers a trip through Xibalbá (the Mayan underworld), a walk through its caves, a swim in the completely natural underground rivers, and the opportunity to admire the breathtaking formations that tell the geological history of the earth. Without a doubt, all of this is a life-changing experience, but now the new “Dry Route” Tour offers even more: a visit to the Salón de la Paz (“Room of Peace”), where a spectacular light and sound show is projected on the natural formations. This experience is sure to transport visitors back in time to the very creation and evolution of the universe.

Contemplate the beautiful scenery of the caves, learn how they are formed, and swim in the crystal-clear waters of the underground rivers. Enjoy the feeling of being truly underneath the ground in a one hundred percent natural environment. Take a seat and observe the history of the creation and evolution of the universe, all projected inside a natural cavern. This is an encounter that can only be experienced in Rio Secreto.
