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.

Not for the faint hearted was hard work going through the cave and best if you can swim but not necessary but the things you see is amazing the staff were amazing even with the less confident in the water the cave was out of this world

This tour was amazing!!!! Our guide was very well informed and really took a lot of time and care in our education , happiness, and safety. He showed a great amount of caution and reverence to our surrounding environment and to the underground river as well. Our accompanying group photographer was top notch providing us with pictures we were able to purchase that we will treasure forever. This is one of the five major excursions my new bride and I were able to enjoy while on our Honeymoon in Cancun and I were able to experience ...this being our favorite BY FAR!!

The trip was affordable, safe, and the large tour bus taking us to the perimeter of the site, had the most legroom of any of the tour buses we were on for the 10 days we were visiting.

Rio Secreto ROCKS!
