Frequently Asked Questions

How thick is the wetsuit?
It is 2.5 to 3 millimeters thick.

If I don’t know how to swim, can I still take the tour?
It is not required that you know how to swim. You only need to know how to float. The in-water portion of the tour is very brief and shallow. In addition, you will be aided by your life jacket and wetsuit, which help you stay afloat.

What is the temperature of the water?
The water is cool, with a temperature of 22º C to 24º C, or 69º F to 75º F. However, our visitors wear neoprene wetsuits and life vests t

Great adventure!

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!

Fantastic adventure. Our guide Felipe was amazing. Photos are much too expensive, we would have bought a photo for $15 but not $25. 2 for $25.

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!

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.
