Exploring the Underground River System
The real highlight is the Rio Secreto underground river—a labyrinth of crystal-clear waters, spectacular stalactites, and stalagmites that glow under carefully calibrated lighting. The tour includes a walk and swim through this underground world, revealing formations that have taken thousands of years to develop. The experience is both awe-inspiring and humbling, as you witness nature’s artistry in a setting few have explored.
The Rappel and Bike Route
One of the unique features here is the rappel into the underground river, which adds an adrenaline rush and a real sense of adventure. Expect to descend into the cavern in a controlled, safe manner, guided by experienced professionals. This activity is roughly the moment where many participants feel the most excitement, as they’re literally stepping into the unknown beneath the earth’s surface.
Before or after the rappel, you’ll enjoy a bike ride through jungle trails. The terrain is manageable but slightly rugged, providing a different perspective of the Riviera Maya’s lush surroundings. It’s a great way to see the flora and fauna up close in a natural setting, and the activity is designed to be accessible for most fitness levels.
Snorkeling and Light Show
After the underground exploration, you’ll have the chance to snorkel in the crystal waters, which are surprisingly warm and clear. The tour also features an entrance to the Dry Route, where a sound and light show enhances the experience, transforming the caves into a mesmerizing display of colors and sounds that tell the story of the site’s geological formation.
Relax and Recharge
A light lunch is included—think buffet style with local flavors—to refuel after the physical activities. The tranquil setting in the jungle provides a perfect backdrop for relaxing and reflecting on the morning’s adventures. Towels and lockers are available, so you can keep your belongings safe and dry.
What Travelers Love and Some Considerations

Based on a review from Kaitlyn_D, who gave the tour a 4-star rating, the rappel was a highlight, though she mentioned a desire to rappel more than once. She also suggested that future visitors might prefer to wear shorts and a swim shirt instead of a wetsuit, which could be more comfortable, especially in warm weather. Her feedback highlights that some might find the wetsuits slightly restrictive or unnecessary depending on personal preference.
The tour’s moderate physical demands mean it’s not suitable for everyone, particularly those with mobility issues or low fitness levels. However, the inclusion of gear and instructions helps mitigate some concerns, and the overall experience is designed to be engaging without being overly strenuous.
The Value for Your Money
While $139 per person might seem steep at first glance, consider what’s included: transfers, equipment, lunch, and the full-day adventure. With hassle-free logistics and access to a unique underground environment, many will find this worth the price—especially if you enjoy active pursuits and are eager to see a less touristy side of the Riviera Maya.
The Sum Up: Who Will Love This Tour?

This experience is ideal for travelers seeking active, hands-on adventures in a natural setting that’s both spectacular and educational. It’s perfect for those who appreciate outdoor activities, and are comfortable with moderate physical effort. Families with older children, groups of friends, or solo explorers eager to add a story to their trip will find this tour both fun and memorable.
