What You Can Expect

Rio Secreto Underground River Tour with Crystal Caves

Visit Rio Secreto Naure Reserve

Your guide will either pick you up at your hotel or meet you at Plaza Kukulkan before departing for Rio Secreto Nature Reserve in the afternoon. Upon arrival, you’ll receive a safety briefing and equipment – including wetsuit, life vest, water shoes and a hardhat with lamp – before your expedition begins!

Follow your guide into Rio Secreto’s underground cave, and admire the stunning crystal-like stalactites and stalagmites as you walk along a path and swim through the turquoise water. Venturing deep inside the cave, take in the peaceful stillness amid the dramatic mineral formations and vivid colors of your pristine surroundings.

When you emerge, enjoy a shower at Rio Secreto’s facility or hang out for a bit in a hammock before returning to the plaza or your hotel.

Was A FANTASTIC EXPERIENCE it is totally a family adventure .I have one small issue with the pick services they gave us a time and we were there at the hotel lobby 5 minutes prior and they had come and gone when I realized that and called the tour company they said they will wait at another hotel and I requested if they could pick us up at the resort they refused so we took a taxi thinking that they were headed in the opposite direction ....once we got on tour bus we realized that they had to circle around after the last pick up and they were going past our resort again ..I did not understand why they could not pick us up when they were going past our resort ... apart from the small incident we were very satisfied and were awe of the crystal caves and their formation ..very informative

AMAZING!!! WE SAW WHAT THE PICTURES SHOW AND MORE!!! This tour, and Julian our guide, were indeed a major highlight of our trip to Cancun. IF YOU POSSIBLY CAN......DO IT!! I am 72, Julian helped me through the rough parts which were not that much. 100% WORTH IT!! They provide everything you need...wet suits, shoes, and lockers for your stuff. I JUST CANT SAY ENOUGH ABOUT OUR WONDERFUL ADVENTURE. The lunch was very good also and all you wanted to eat.
