This was a beautiful unground cave system. Gabby was a really great guide, she was very informative and made sure we got the most out of the experience. Would totally recommend going to if you get the chance.

It was Awesome!
Roxana_V, Sept 2023
A Memorable Adventure!! it's hard to put this experience into words, so I recommend you try it out. we hiked on rocky ground, there is some swimming involved, but any challenge was worth it. Mely was a thoughtful and knowledgeable Guide.. verbally guiding us through each rise and dip as we hiked in the river. We took advantage of the hiking sticks offered. The Helmets and Life vests are mandatory.. glad I had my helmet on in some of those small spaces. Wet suits are provided, but my husband and I felt the water temperature was fine, so we chose not to wear them, which turned out well. The Lunch Buffet was Excellent. We had chosen to add the Tulum tour, which we did before the River hike. What a Beautiful place! I feel the restoration process is being well done, and grateful that Vendors have not been allowed to set up amongst the ruins. There was plenty of good shopping outside. I am glad that we got the opportunity to add this to the Tour. Thank you.
Bucket List Crossed Out
Ruben_F, Sept 2023
The tour was amazing breathtaking scenery, our tour guide Tainara, is well informed and knowledgeable w/ Rio Secreto & Tulúm history. If you need a tour guide that can speak Portuguese, Spanish or English she’s your best and only option.
Unforgettable experience
Sarah_W, Sept 2023
The caves were an experience I will never forget. It was so neat!! The water was so wonderful. Alfredo was an informative and fantastic guide. The food after the cave was amazing. I have never experienced anything like it before.
amazing magical cave tour
Dorine_F, Sept 2023
Guide ( leslie) was funny and took good care of the group. The cave tour was one of the most amazing things I've ever done. ! Buffet was 6/10 but the cave was the main event. Wear the wet suit! water is cold for 1.5 hours in the cave . Ride to cave was 1 hr 40 min in and 2 hours on the way back to cancun. But totally worth it. I wish we could have spent more time in there .( like alld ay !) Pictures were expensive and you can't take pics in the cave. You feel like you're the only tour in the cave as I am sure the # of people are limited. Magical experience! just go !
On your bucket list now
Shawn_S, Sept 2023
WOW! JUST WOW!! I loved this almost as much as diving with the whale shark. Then again there are many places to dive with them and the Rio Secrete is an experience not to be missed. If you’re looking to do something amazing when in the Mayan Riviera- this should be first on your list.
Response from Host, Sept 2023
You are definately right, Rio Secreto is a place that can be missed if you are in town and of course one of our customers favorite experience. Thank you for sharing

Unique and beautiful experience
Aly_c, Aug 2023
This was such an amazing excursion! Our group was small- only 6 people and our tour guide. It was so unique. The tour guide was so informative and gave us such great information full of history and science! It was beautiful and also so refreshing! It was maybe 70 degrees inside the cave when it was 93 outside! This is a tour we would actually repeat!

A great adventure
Catherine_L, July 2023
Amazing adventure! The best guides! It is a long car ride but totally worth it. We booked with the ruins tour but changed to the deluxe tour when we found out the ruins was another hour drive each way. They were very accommodating.

Thank you very much for writing a review, we are really glad to read you enjoyed the trip and that our guides made a nice job.
DO NOT MISS THIS EXPERIENCE - Otherworldy, magical, beautiful, awe-inspiring!!!!!
Chana_B, July 2023
My husband and I did this tour in July 2023 and it was truly one of the most incredible experiences of our lives. It cannot possibly be described in words. The beauty and magic of the Rio Secreto caves was absolutely awe-inspiring. Anyone who ever has an opportunity to do this - DO IT!! Try to get on a tour with Anna as the guide - she is epically incredible. Be prepared to walk on uneven ground, do a little bit of actual climbing and navigating narrow parts of the path that require a basic level of physical ability, be prepared to get wet (you don't need to know how to swim) and be prepared to be absolutely astounded. Every single aspect of this tour is professional, thought through, well organized, and just amazing beyond words. They genuinely care about your experience and do everything they can to help each person get the most out of it.
Response from Host, July 2023
Thank you very much for sharing your experience, we are really glad to see you enjoyed the trip. It is very nice to see that the guides make an excellent job, for sure they will be advised about the great job they did.
Best tour in Mexico
Karen_B, July 2023
By far, the BEST tour we did on our Summer vacation to Cancun. Absolutely unforgettable! Paulina was an amazing guide. She was so knowledgeable, friendly and helpful. I don’t know how to swim. She made sure I felt safe and comfortable at all times. My teen sons and husband had the best time. This is a must do!!
Response from Host, Aug 2023
Thank you very much for the time to write the review, we will let your guide know about the great job he makes with you during your tour. We hope you enjoy the next time.

This was an absolute blast. Our guide was extremely knowledgeable and the buffet was delicious. The cave itself was the best part. I’d highly recommend this excursion

Rio Secreto was amazing
jennifer_t, July 2023
Rio secreto was amazing and the best part of the entire tour. Advice is to skip the tulum ruins as they arent as interesting as chichinitza, but the cave system at rio secreto was so cool and an incredible experience. Our tour guide qas also extremely knowledgeable and very informative as well as nice!
The guide from Brazil is...
Diana_D, June 2023
The guide from Brazil is very nice and knew a lot of information it’s going to be hot during the Tulum ruins tour make sure to ask how much before taking pictures with the monkey iguana in Tulum even the guide mentioned this to make sure you ask for pesos or dollars bring cash for things you can’t pay with card don’t need to change your money they accept usd I wished I could of gone to the beach but the guide said it was closed for the turtles to lay eggs I wished I could of bought passion fruit tequila from the store there but I have a carry on the cave you need a wet suit and use the stick because you can’t touch the formations unless the guide tells you it’s ok to touch certain places you have to watch your step and above you the food was good better than the extreme adventure where you only got two tacos here is a buffet pictures are expensive can’t bring a camera or a phone I only got one picture since it’s 25 a piece or 99 for all

Amazing experience
Paulette_K, June 2023
Super fun adventure, Diana Wonder Woman was our guid and she did an amazing job. The cave is a very unique experience. Even though I don’t swim I still was able to enjoy the full tour without any issue. Telum is hot but worth to visit. Overall it was a great experience. Be prepared to come back super tired since it is a full day activity:) you will not be able to take any phones but the photographer is really good at capturing everything and the phone package cost is 100 US dollars: but worth it.
Response from Host, June 2023
Thank you very much for sharing your experience, we are really glad to see that Diana make an excellent job during your stay. We will share this comment with our team in order to keep improving. As you mention, the phone is not authorized, however, we have great photographers.
Great Tour
Gail_P, May 2023
Omar was the best tour guide. As an older person he helped me along the river. The river part of the tour is very intense, the bottom of the river is very uneven.
Response from Host, June 2023
Thank you for sharing your feedback through this means. Your comments are truly valuable for us, as it allows us to improve our service levels and product.

Victoria_S, Apr 2023
This was the best experience this vacation. Expencive, but worth it. The duration of the day was perfect as well
Response from Host, Apr 2023
We are so grateful for your kind words. Thanks for sharing your review with us and the community
Worth it. Caves amazing. Tulum was so hot tho.
COTYANN_C, Apr 2023
Tulum was so hot! They needed misters or a way to cool off. But neat, our guide Diego was knowledgeable and great. The caves were awesome, great photos taken by photographer and reasonable price. I wish the advertisement (on Viator) was more clear on what to wear. It said wetsuits provided, so we thought it was required to wear wetsuit so we did not bring any other swimwear, but you can totally wear your OWN swimwear! Shoes and life vest provided were good. Our guide, Diego, again was great, full of info, and helped make the cave water trek safe. Buffet restaurant at the end was good. Transport was good. Overall very cool. If we could redo it, we would only do the Rio Secreto part and not Tulum.
