We cannot express how memorable this tour was. As for natural wonders, it exceeds any other cave or underground experience because it is untouched by human hands. If we were in the same location 2000 years ago, the sights would be the very same. No man made lights, paths or modifications. What an opportunity not available anywhere else in the world.
It was very safe and the guide was excellent. A must see!

Awesome tour!! An experience to remember forever, and Victor was a wonderful tour guide! It can be a little dangerous so be sure to walk slowly and carefully and be able to swim. Exiting the cave was a little scary because the water level was quite high due to rain the previous day, but Victor led us through very well. Very glad i did this tour!

What a trip!!!! This tour was simply the highlight of our trip. Fantastic tour guide, amazing sites and the lazy swimming was fun too. The guide even helped my girlfriend who couldn and #39;t swim. Definitely a must see if you and #39;re headed to the Yucatan peninsula.


5 star rating: Highly Recommended January 2016

The tour of the Rio Secreto was perhaps the most favorite thing we did on the whole trip. It was a most beautiful site to see and our guide Pablo was fantastic!! Team Canada and Team USA will never forget the Doggie Paddle story. This is tour than anyone and everyone should do while visiting the Yucatan.

Great afternoon out. The caves are amazing and the trip was a great success for the family. There aren't many caves you can go into in the UK which aren't a 'no go' area! We spent about 1.5 hours swimming and walking through the caves. An fantastic experience. The food that was included later wasn't great. There was lots of it and it was warm but there wasn't a great selection.

I loved the underground tour and the guild was incredibly informative and helpful.

The photographer did s great job of the photos but they were expensive and there didn and #39;t seem to be a fixed price.

The tour through the actual caves was incredible and a really worthwhile experience. The equipment, guide, Ramon, and safety features were all spot on and the food provided was interesting and very enjoyable. My one reservation is the cost of the photo package, as we were a 'captive audience' and no cameras were allowed inside the caves, if we wanted a record of our visit we had no other option than to buy the offered photo package. Compared to the photo package at Cenote Maya Park which contained many more photos this package cost twice as much, not good value for money. Apart from that it was a very enjoyable half day trip.

The tour is good, the color looks great on pictures, however inside the cave, there's no lights at all. The online photos look great but actually it's just dark inside the cave.
