Great adventure! Score: Recommended: YES from Oklahoma City
Ari was a fantastic tour guide! He did everything and was an incredible speaker in both languages. Very knowledgeable, entertaining, friendly, and fun. Not only did he help us through the cave and other activities, he even brought us tortillas during lunch, cleaned eveyone’s tables, and drove everyone home! He’s the best tour guide we’ve ever seen anywhere in the world and he deserves a promotion! Thank you, Ari! Score: Recommended: YES from Kansas City, KS

We loved Benito! He was a wealth of information! The terrain is a bit intense, so I used a walking stick and it saved me several times. Next time we are back in the area, we will do the tour again but a different part of the cave system. It was THAT cool! Score: Recommended: YES from Oregon

The tour was amazing Score: Recommended: YES from New Jersey
The only complaint I have is that the constant photography was distracting to say the least. You are trying to maneuver through the water and you have the photographer constantly asking you to pose. I would definitely make my feeling known about no photography if I venture into another cenote since it was very intrusive while you are trying to enjoy the experience.

This was incredible. Santi was extremely knowledgeable and entertaining Score: Recommended: YES from Woodbridge,VA

This was a great experience made even better by the fact that we had a very knowledgeable guide, Benito. Score: Recommended: YES from England
The guide was GREAT and helped me immensely as I had difficulty with the walk. Frankly, it was too strenuous for me. I've swam in cenote caves before without a life jacket, which I can handle but the trek with the rocks was beyond my capacity. Score: Recommended: NO from Asheville, NC
Definitely one of the highlights of our vacation. Our guide was knowledgeable, witty and made the experience memorable. Score: Recommended: YES from Mission Viejo, CA
This tour far exceeded our expectations. We have already recommended it to everyone and we will definitely come again when we visit Cancun next year.

Totally amazing! Our guide, Epco, was very knowledgeable and super friendly! When you first get there you watch a video in your preferred language and then they give you a guide that speaks your language which makes it much more enjoyable. We would definitely recommend this activity and we want to return ourselves soon! Score: Recommended: YES from Hanford, Ca.
I have been to Carlsbad Caverns in New Mexico,which is a lot bigger than Rio Secreto,but you walk on a paved path and everything is well illuminated.Rio Secreto is just the opposite.No path,hardly any illumination.You truly feel the adventure of being in a cave.It was also exciting to see bats and a cave spider.Lunch was a buffet which also had enough vegetarian options and we got to taste the "ixtabentun",an anis flavored liquor.This was one of my best tours out of Cancun. Score: Recommended: YES from Vista, CA
It was a really good time. Score: Recommended: YES from San Diego, CA
