Rio Secreto was awe inspiring and and an absolute otherwordly experience. It is a truly fascinating and wondrous place. When in the area and looking for a unique and memorable adventure, this should top your list. I even took my 7 year old daughter and she had a magical time! more

I went to Rio Secreto in mid October and it was amazing. The cave was very unique. It was lucky for us because on our trip to Mexico the only time it rained was when we were in the cave. The weather does not effect this excursion at all because you are underground. It may even make it better when... more

Stepping down into the caves, was like entering into a different underworld, dazzling, serene, and creepy all at the same time. Untouched by humans, the caverns seem to swallow you whole, and it's almost like you dont know where to look first to take it all in.

Fernando is an excellent guide whose enthusiasm for the caves was contagious! My son & I are extremely claustrophobic and we never,... more

OMG....I don't know if I have the words to describe the experience. It was absolutely breathtaking and unbelievably beautiful. more

I was quite skeptical after my husband brought up the idea of this adventure but after some convincing and research, I gave in and I am so glad I did this in September 09! We booked through our resort for the next morning (picked up at 7:45 a.m. ) and a short trip on an air conditioned van, we arrived... more
