1 of a kind experience!
Such a special experience and easily one of the highlights of our time in Playa del Carmen. Pet Cemetery cenote was absolutely magical, but Juan is what really made the day memorable. He was warm, funny, knowledgeable, and made the whole experience feel genuinely personal rather than just another tour. You can tell he really loves what he does. We left feeling incredibly lucky to have had him as our guide. Thank you, Juan!

Cenote Tour with Eduardo
This is a private tour that includes an underground cenote and an open cenote (in our experience). The underground cenote is a unique & incredible adventure, but maybe not a great idea for people who experience claustrophobia or don't enjoy caves.Eduardo is a fantastic tour guide, pointing out small details one would otherwise miss if not familiar with the caves (silk worms, calcified tree roots, etc). The cenotes he took us to are not popularly travelled. However, they are peaceful, relaxing, and beautiful. The underground cenote requires more physical work to get through, but is not difficult. The open cenote is swim/snack/relax at will.Our guide, Eduardo: He's knowledgeable about the cenotes, and clearly loves the environment he both works in and protects. His demeanor is friendly in a familiar way, making the trip feel like you're hanging out with a friend versus being a tourist. My husband and I had a great time exploring the cenotes, and he was a large contribution to that.Thank you, Eduardo!

Amazing Cenotes adventure with swimming and underground cave exploration. A must do while in Tulum!
We had the most amazing experience with Juan. His English was excellent and he was very knowledgeable and personable. We had such an incredible adventure swimming in the cenotes and exploring the underground cave system. This excursion is worth every penny! I highly recommend this activity. Juan is the best guide!

Fantastic private tour of hidden gem cenotes
A perfect visit to cenotes that are off the beaten path and absolutely gorgeous. We had both sites to ourselves for a good portion of our tour. Juan was such a lovely guide—so knowledgeable about every aspect of what we were seeing. Having someone who understood the history of the place as well as the environment and ecology added so much to the visit…not to mention flawless English and great junky snacks that we just can’t get in the States :). Pro-tip: recommend you accept the shortie wetsuit if you tend to get cold while snorkeling. Highly recommend!!

Fun experience at Cenotes
Fun experience. I would suggest keeping conversations light - Guide was easily offended by the notion that a part of Mayan history (like every culture’s history) involved violence. When discussing Mayan culture and mythology, the guide asked if we knew about Pok-ta-Pok. I responded “Yes!” (having been fascinated by Mayan culture for years) and referenced the use of a decapitated head. Before I could finish my sentence (about Popol Vuh and other historical or mythological references I’d learned), the guide scoffed and said “No, that’s ridiculous.” - It felt really strange for someone to take offense and make it seem as if I had insinuated that violence is the only aspect of Mayan culture. I thought I would clarify by saying that I didn’t think it was a bad thing and that every culture has different aspects of violence in their history. He laughed and made a comment about how there are still places where people are killing each other, referencing the United States without saying it. The vibe was just weird after that - Overall, the tour through the Cenotes was amazing, just would have preferred a guide that wasn’t easily offended by a conversation that shouldn’t offend anyone.

Coolest experience!
We had the most incredible cenotes trip with Eduardo, and we cannot recommend him enough. From start to finish, he made the entire experience feel so personal, fun, safe, and unforgettable.Eduardo was warm, knowledgeable, and so easy to be around. He shared so much about the area, the cenotes, and Mexican history and culture, which made the experience feel so much more meaningful than just a tour. You could tell he genuinely cared about making sure we had the best day.The cenotes themselves were absolutely stunning, but Eduardo made the trip even better. He knew exactly where to take us, helped us feel comfortable the entire time, and made everything easy and relaxed. It never felt rushed or overly touristy — it felt like such a special and authentic experience.This ended up being one of the highlights of our entire trip. If you are visiting Tulum or the Riviera Maya and want to see the cenotes, book with Eduardo. You will be so glad you did.

Best Cave and Cenote Tour!
I’ve been going to the Mexican Riviera are for over 30 years and I can’t believe I’ve never done this tour before! We had the beautiful crystal clear waters of the privately owned cenote to ourselves and the caves on the second part of the trip were otherworldly. This is a great way to beat the Mexico heat and enjoy a truly unique experience!

Juan made the entire cenote experience unforgettable. He was incredibly knowledgeable, not only leading us safely through the caves but also sharing the history, geology, and cultural significance of each cenote along the way. You could tell he genuinely loves what he does, and that passion made the tour so much more meaningful.He kept the group engaged, answered every question, and made everyone feel comfortable exploring areas we never would have discovered on our own. If you’re visiting the cenotes, I highly recommend taking a guided tour—especially if you’re lucky enough to get him as your guide. An absolute highlight of our trip to Tulum.

My Johanna and I want to thank Juan for a very special day! The underground river/cave float was spectacular and a once in a lifetime experience. Juan was very informative and attentive to our needs.

Wonderful Tour and Guide!
Eduardo was a wonderful guide! He was friendly and well accommodating, and provided lots of time for us to enjoy the first cenote to ourselves. Clean vehicle and snacks included! He was very fun and even had great recommendations for the remainder of our trip. The first cenote we arrived right away and was private to enjoy without crowds. He even took photos for us while we enjoyed the swim. Sac Actun was the highlight of our vacation, and he had great information and made it so fun! Would highly recommend a private tour with Eduardo for any adventure!
