Transportation and Group Size
You’ll be picked up directly from your Cancun hotel, with the ride in a sanitized vehicle to ensure health safety. This convenience means avoiding the hassle of arranging transportation, especially for a day that involves a lot of physical activity. The tour caps at 22 travelers, which helps foster a friendly atmosphere and ensures you won’t be part of a giant, impersonal group.
Starting Early for an Action-Packed Day
The tour kicks off at 7:00 am, a smart move to make the most of the day and beat some of the crowds. While early mornings aren’t everyone’s favorite, arriving early means cooler weather and better light for the activities ahead. Plus, it leaves plenty of time for relaxation or exploring afterwards.
Jungle Exploration and Cave Biking
The first part of your journey involves a guided tour of the jungle, where you’ll get close-up views of the lush greenery and possibly spot local wildlife. The highlight, however, is biking inside underground caves. According to reviews, this part is exhilarating and uniquely memorable—travelers have described it as “incredible” and “a surreal experience.” The equipment provided is suitable for the activity, and guides like Carlos or Miguel are known for their friendly, informative approach.
Caverns on Foot
After biking, you’ll switch to walking through a series of mysterious caverns. These natural formations serve as a geological library, with stalactites and stalagmites telling stories of Earth’s history. Reviewers mention the caves as “enchanting” and “magical,” with some noting that the formations appear almost otherworldly. Be prepared for uneven surfaces and a fair amount of bending or crouching, but the guides will ensure safety and offer tips along the way.

Snorkeling in the Underground River
The tour’s pièce de résistance is the swim and snorkel in a crystal-clear underground river.

The water temperature is usually comfortable, and the guides make sure everyone is equipped with snorkeling gear. Several reviews highlight the beauty of the underground river, often calling it “breathtaking” and “peaceful.” The experience of floating through this natural wonder is truly one-of-a-kind.
Post-Adventure Relaxation
Once your exploration wraps up, you’ll enjoy a regional buffet lunch in the eco park’s dining area—an excellent way to refuel after a busy day. The food is described as tasty and filling, featuring local flavors. Afterward, you can unwind in the “room of peace,” a quiet space for reflection and calm before heading back to Cancun.
What’s Included and What You Should Know

The tour price covers admission to the eco park, all equipment for biking and snorkeling, lockers for your belongings, and the lunch buffet. This all-in-one package is a good deal considering the number of activities and the natural wonders you’ll encounter.
However, note that photos and videos are not included, so if you want to document your adventure, you’ll need to bring your own camera—though during the activities, cell phones are not permitted for safety reasons.

You can cancel for free up to 24 hours in advance, which offers peace of mind if your plans change or if weather conditions turn unfavorable. The experience is weather-dependent; if rain or storms interfere, the tour may be canceled or rescheduled, with options for a different date or a full refund.
