Extremely amazing experience at Rio Secreto!!!

This was an amazing experience. I've been to caves before, but being able to swim through a cave was next level for sure. If you want to do the most amount of swimming, request the enchanted section of the tour. The tour guide Allen was awesome, and the photographer was amazing as well, JD if I remember correctly. Please please, tip and take care of these guys. They are very dedicated to the experience and also very caring for nature.

Welcoming and Fun

We visited Rio Secreto as our weekly excursion offered by or hotel. It was a once in a lifetime experience. We do not speak spanish, however, I felt like the company pairs groups together and we were in a group with all English speakers which I felt was a nice accommodation (so a guide doesn't have to say things twice). Our tour guide Pepe was amazing. He was super fun, knowledgeable, and easy to understand and follow. The entire tour was super welcoming and all the staff we met along the way were so friendly. We will always recommend this excursion to others who come to Cancun.

Recommended!

Super fun/beautiful experience! Definitely recommended! Unfortunately you are not allowed to bring your own cameras....There is a photographer, but they charge 120 dollars for the photos...very expensive unfortunately.

Is Heaven underground?

No words can describe what your eyes will see and what your soul will feel in that place!! You go for the tour and you come back full of thoughts and feelings!!! Jenifer, the tour lady, will give you with a very expressive way, all the knowledge you need about that phenomenon !!! And not only this. My friend who couldn’t walk very well, he received so much help from her!!! She is physically so strong!! She supported him , lifted and pulled him all the way through the exit and made it happen for him. Thank you Jenny!!!!!
