Before the completion of the dam, the waters that ran through it were not passable, even for the most skilled boatmen. Once the river was dammed, the water levels rose dramatically, creating an extremely deep and serene river, where tour boats and taxi boats could navigate with ease. The Chicoasen hydroelectric dam opened in 1981, and today is considered to be one of Mexico’s most important sources of electric power.
A traditional Sumidero Canyon tour would consist of travel to one of the vantage points if you want to get a bird’s-eye view of the canyon, but if you really want to experience it properly, take a boat ride. The most common embarkation point is at Chiapa de Corzo, a short drive from Tuxtla Gutierrez.
The 2 to 3-hour round trip on the boat will take you on a spectacular journey through the canyon, with some of the walls towering 2,500 feet above you. The wildlife on display is rich and particular to Mexico, and your boat may take you on a tour past one or two caves in the area.
A new Ecological Park has been opened inside the canyon, which offers a range of activity-based eco-attractions including the opportunity to visit the wildlife sanctuary, see local flora and fauna as well as a number of physical and sporting activities such as kayaking, mountain biking, abseiling, zip-line, swimming and more.
A breathtaking experience of never-before-seen views, and an authentic reflection of Mexican culture and its variety, Sumidero Canyon should not be missed when you are traveling to the Chiapas area.
