Sumidero Canyon: Stunning Natural Beauty, Abundant Wildlife, and Environmental Challenges
Nestled along the popular Gringo Trail, the enchanting colonial city of San Cristóbal de las Casas in Chiapas, Mexico, invites travelers to linger. Yet, allocate a morning for an unforgettable excursion to Sumidero Canyon, located just 48 kilometers (30 miles) east.

Comparable to the Grand Canyon on a smaller scale, Sumidero Canyon offers breathtaking views from five scenic viewpoints along the rim, easily accessible by rental car. For a truly immersive experience, however, embark on a boat tour along the Grijalva River that sculpted this wonder. Far more approachable than its U.S. counterpart, the 35 km journey culminates at Chicoasén Dam, a vital hydroelectric power source for Mexico and neighboring Guatemala.
We strongly recommend the boat tour, where vibrant wildlife along the riverbanks and the sheer 1 km-high canyon walls create an awe-inspiring spectacle as you gaze upward at the surrounding peaks.


Sumidero Canyon features numerous waterfalls, many hidden from roadside viewpoints. The iconic Árbol de Navidad (Christmas Tree) stands out, with water cascading from a crevice onto moss-covered rocks resembling holiday branches. Boat photos reveal its impressive scale.



Birdwatchers will delight in herons, pelicans, and more, but the star attractions are the 400 resident crocodiles—some reaching 6 meters—lurking in the Grijalva River. Keep hands safely aboard as boats glide by to avoid tempting these predators.


Regrettably, pollution mars the experience. Media reports highlighted waste washing into the river during rains from nearby villages. While most areas remain pristine, a notorious bottleneck accumulates Styrofoam, plastics, and debris, challenging boat navigation.

This stark sight tempers the natural splendor, underscoring conservation urgency. Witnessing countless plastic bottles inspired our commitment to reusable containers over single-use plastics. Past sewage diversions from Tuxtla Gutiérrez (now redirected) compounded issues. Still, the trip is essential, offering profound lessons in environmental stewardship.
Once a contender for the New 7 Wonders, Sumidero has launched extensive cleanup efforts, with dedicated workers and biodiversity experts optimistic for a cleaner future—benefiting wildlife and visitors alike.
