It was a unique experience and very beautiful. The guide was very good. The only issue was there were too many pauses for picture taking.

The actual tour itself was very interesting. The transportation back and forth was too long. We were told it was a 5 hour trip.... it was closer to 7 hours by the time we got dropped off at our hotel.

Awesome!

A stunning place with a great underground river! A bit cold but worthy! And it's so hot outside that this is a great way to cool yourself.

Stunning place, definitely worth visiting.

Loved this tour! They took us through caves and rivers. A true natural wonder it is! It was cold though but in the warm weather you'll this place.

One of the most beautiful places I've ever been! Loved the underground rivers!

One of the best experiences of my life!

A great tour for explorers! We loved it, I wanna go back!

The rock formations in this place are incredible. So much fun swimming in the underground rivers! Don't miss it on your visit to Cancun

They don't lie qhen they say this place is like a natural museum... absolutely amazing!

Absolutely amazing !

I'd never thought a place like this existed, simply stunning! It was great to go through all these caves and rivers. Makes you feel humble to Mother Nature.

This experience was like nothing before. It's like traveling to the very center of the Earth and swim in underground rivers to explore rock formations and lot more. A great tour!

We went with no expectations and what we found is an amazing underground world! the rock formations are incredible and we felt like explorers going through rivers and caves. Amazing place!

Indeed a pleasant experience, loved every moment of it!

It's a beautiful place but not fun if you can't stand cold water.

Amazing place, beautiful caves and underground rivers. Worth visiting many times.
