Good adventure on a hot day.

We enjoyed the experience in the cave. I was pleased to see that the guides were light-hearted and helped me to cross some tricky sections. The guides were knowledgeable and entertaining as well. I enjoyed the presentation on cave geology. We were able

Must do activity when in the region

This is a must do activity when in the region! The natural beauty and uniqueness of the experience was amazing! Our guide Pepe was beyond impressive with his knowledge and dedication as our guide! Cost was reasonable with hotel transportation! The duration was just under 2 hours in the cave pic up at 9 and was back at our resort by 4 pm. Without reservation please enjoy this experience!

Well put together tour,...

Well put together tour, lots of visitors but they have a nice flow so that it doesn't feel crowded. Everyone goes into different sections so you have your own private tour inside the caves with about 8 people and a personal photographer. The caves are beautiful and Pepe our guide told us everything about them, he was wonderful. Photos cost $35 each for a digital copy. Definitely recommend this trip!

Good excursion for a day trip!

Aaron was a great tour guide! He was very knowledgeable, friendly, and overall great to spend the day with. When checking in for the activity the day before, it would have been nice to be reminded to pack a change of clothes, potentially your own water shoes (as you borrow them at the Rio), and that the ruins (if you opt in for the Tulum part) will be very hot in the afternoon. The main dislike is that the transportation vans are really a tight squeeze and smelled soggy from people wearing their bathing suits on the seat material. Viator should have direct links to the Rio Secreto directly, to get more information on what the day will look like. Overall, we enjoyed this excursion and would recommend.

Put it on your bucket list

We did the cave tour with Manuel and it was fantastic! I highly recommend it. It is a unique incredible experience. No camera's allowed so expect to pay $$$ after for the ones they take.
