Discover Chiapas' underground world with a full-day tour at El Chorreadero, featuring hiking, swimming, rappelling, and breathtaking natural sights.
Planning a trip to Chiapas and craving something a bit more adventurous? If so, the Underground Adventure at El Chorreadero offers a full-day escapade that combines scenic rugged landscapes with the thrill of exploring subterranean waterways. This experience is ideal for travelers who enjoy outdoor activities, natural beauty, and a splash of adrenaline.
What we particularly like about this tour is how it showcases Chiapas’s wild side—climbing, jumping, swimming, and rappelling through natural formations. Plus, the guides are certified, ensuring safety and an enriching experience. On the downside, it’s a long day (around 10 hours), which might be tiring for some, especially if you’re not used to physical activity. This tour suits active travelers and those eager to see Mexico’s underground marvels firsthand—just remember, it’s not recommended for children under 12 or anyone with low fitness levels.


Imagine stepping into a world where the familiar becomes extraordinary. This is what the El Chorreadero underground tour promises—a 10-hour journey into one of Chiapas’s natural wonders. Starting with a transfer from San Cristobal de Las Casas—a scenic drive of about an hour—you’ll leave behind the bustling streets and plunge into a landscape that seems almost untouched by modernity.

The trip begins with a convenient pickup from your hotel, included in the price, which means less hassle and more time to focus on the adventure ahead. Expect to wait no more than 10 to 30 minutes as guides coordinate your departure. The drive itself provides a glimpse of Chiapas’s lush scenery, setting the tone for what’s to come.
Once at El Chorreadero, you’ll pay a park entrance fee that’s included in your ticket—no hidden costs. Here, your guides, certified and experienced, will equip you with safety gear and provide an overview of the day’s activities. Their local knowledge adds depth to the experience, offering insights into the geology and ecology of the area.
The heart of the tour is accessing the underground river. For roughly six hours, you’ll engage in a series of activities that make full use of the natural environment:
The combination of natural beauty and physical activity means you’ll find yourself immersed in an environment that’s as challenging as it is breathtaking. Several reviews highlight the fun of jumping into clear waters or sliding down natural rock formations—”a wild ride in the best sense,” as one participant put it. The guides’ professionalism and safety briefings are repeatedly praised, making it accessible even for those new to adventure sports, provided they’re in decent shape.
Given the physical nature of the tour, it’s not best suited for children under 12 or those with low fitness levels. You should wear comfortable shoes, pack a change of clothes, and bring a sense of adventure. The tour doesn’t include meals or beverages, so you might want to carry snacks or plan to eat before or after.
After a full day of climbing, swimming, and exploring, you’ll head back to San Cristobal, tired but exhilarated. Many reviews mention how the experience leaves them with a sense of accomplishment and a new appreciation for Chiapas’s natural landscape.

At $120 per person, this tour offers a well-rounded package of transportation, expert guides, park fees, and insurance—elements that can otherwise add up if you were to organize activities independently. For adventure lovers, the chance to traverse rugged terrain, rappel, and swim through underground rivers all in one day is a rare find, especially in a setting as pristine as Chiapas.
While the price might seem steep for some, the inclusion of safety measures and professional guidance adds peace of mind. Plus, the experience’s authenticity—climbing natural formations, swimming in underground waters—means you’re not just ticking off a tourist attraction but genuinely enjoying nature.

This adventure is best for active travelers who enjoy physical challenges and are comfortable in outdoor environments. It’s ideal if you’re looking to escape typical sightseeing and want a story to tell—something more visceral than museum visits. Families with older children (over 12) and fitness-minded individuals will get the most out of it.
On the other hand, if you’re not keen on getting wet or climbing, or if you prefer relaxed, cultural experiences, this might not be your best fit. Keep in mind the long hours and physical demands when deciding.

The San Cristobal underground adventure at El Chorreadero offers a compelling way to experience Chiapas’s rugged side. It’s an active, engaging day that takes you beneath the surface—literally—into a natural world filled with surprises. The combination of hiking, jumping, swimming, and rappelling makes for a unique adventure that appeals to thrill-seekers and nature lovers alike.
The tour’s well-organized structure, coupled with certified guides and inclusive pricing, makes it a practical choice for those who want to maximize their time and effort.
