  • Overall: This tour was amazing. I highly recommend it. Solo, group, kids - great for all ages.

    I got picked up from Cancun so the ride down was about an hour or so. I completely forgot the name of the bus driver and chaperone, but they were great. The chaperone was funny, he kept the bus alive with his little jokes at 7:00 AM. Once you get to Rio Secreto, you are divided into language groups English and Spanish/Portuguese - I believe I heard some French, too. From there you take a van to meet up with your tour guide to get prepped. The ride is about 10 mins and it's a bumpy, dirt road so if you get motion sickness take some non-drowsy dramamine or chew on some ginger. Once you arrive to meet up with your tour guide, you will be taken to the lockers and shower. They require you to shower before heading into the river. Also, no earrings, watches, etc. in the river. After that you'll be given water shoes, helmet with light, wetsuit, life vest, and a hiking stick if you want one. I highly recommend the hiking stick. There's a 5-10 mins hike down to the river - the path is uneven, slippery, and there are some poisonous plants and trees on the way to the river so you don't want to trip and land on something that can harm you. Right before you head down the river you will be blessed by a Mayan shaman. You can opt out of that if you want. After the blessing it's time to head down to the river. Words cannot even describe the feeling you get just looking at this place in person. If you think the photos are beautiful just wait til you see it with your own eyes.

    Unfortunately, there are no cameras of any kind allowed, but they do have a photographer following you taking photos for purchase at the end of the tour. Price per photo is 25USD or purchase the entire package for 99USD. I purchased the package because our photographer was great, and I wanted memories of this magnificent place. The photographer was really happy I liked his photos after I told him I was going to purchase the package. We only get to see 10 of a really long and deep underground river that's still being explored and mapped out til this day. The revenue from this tour helps conserve and protect the rest of the river/nature reserve which is roughly 1.5 million years old - let that sink in no pun intended. The buffet they provided after the tour was decent. It's food, and I was hungry so I ate it. Don't expect to be given Michelin star food or authentic Mexican cuisine here.

    My tour guide was Lu. She was awesome. She provided information about the river, history, and made sure we didn't slip or fall by lending out her hand every time we came across a difficult path. I went on this tour solo and was grouped with some older folks - which I love. My group was lively and entertaining. We all looked out for each other along the way. In the end, I'd do this tour again as they continue to discover more of this underground river.

  • This was our second visit to Rio Secreto. Wonderful experience with an awesome guide. Well worth the money.

  • This was an amazing tour and well worth the time away from the all-inclusive resort. Our tour guide was very knowledgeable and passionate about preserving a natural treasure.

  • This tour was very special. Going into this wonderful cave with an excellent guide like Carlos was an amazing experience!. He managed with a lot of skill and safety two groups in different languages. Very recommended tour and guide.

  • We enjoyed our experience at Rio Secreto. Our tour guide Alondra was great - knowledgeable, funny and very friendly. You're not allowed to take your camera/phone with you which is understandable cause you're constantly in and out of water, on uneven terrain etc.... But unfortunately, our photographer didn't do a good job. We only selected one photo to take home cause we wanted at least a photo to remind us of the experience! Photos are US25 each but you can choose a package for more money. We weren't pushed into purchasing photos, unlike many reviews I had read. Lunch was OK. Overall, a great experience and well worth it!

  • This is a must see in Mexico!

  • I'd give a 0 rating to this trip, because of the POOREST OF THE POOR Customer Services. I had mentioned very clearly my pick up location in the Hotel Zone Cancun, but I waited there and nobody showed up for pick up. Upon calling the local tour phone number provided on Viator voucher, I was told that I had not selected Hotel pick up. I have proof on the voucher that clearly mentions Hotel Pick up with the location address. I was told in the last minute I'd have to get my own transportation to the venue, but I would not have made it to the tour in time. I ended up not going at all. Complete waste of money and precious vacation time.

  • Awesome trip! Both the driver and the tour guide were excellent! I would highly recommend this.

    Tour was amazing and fun, guides friendly and helpful!!! I want to make that clear.... that was great!!!
    BUT!!!!.....we go on holiday to make memories, and we want to take pictures we can cherish and remember and show our loved ones. However, for some reason you cant take your phone or camera.... ok i accept that..... however we know its a ploy as they are allowed to take pictures etc to sell to you..... anyway, they wanted 99USD for all pictures or 25USD for one.... that's just terrible!! I asked for soft copies to be emailed at a reduced fee... no.. wouldn't budge on the price. So this is why it has 2 stars... its expensive as it is.... its a few hours... not a whole day... so when they try to rip you off, clearly and obviously, I get annoyed. p.s. I cant share a picture as I didn't want to pay 99usd for all of them!

  • This was the most awesome trip our guide Nunes was wonderful and they took us in groups of 10 which was super ....the lunch was something to ask for ...they could have given us way better food need not be fancy but atleast flavorful ?? we were not a fan of the food at all here but trip was very exciting and well organized.
