Sumidero Canyon (Spanish: Cañón del Sumidero) is a narrow and deep canyon surrounded by a national park located just north of the city of Tuxtla Gutiérrez in the Mexican state of Chiapas. The canyon is about the same age as the Grand Canyon since they formed as a result of the same geological shifts. The canyon has vertical walls which reach as high as 1000 meters, with the river turning up to ninety degrees during the thirteen kilometers that the narrow passage runs.
The sights were spectacular. We took a boat ride through the entire canyon ending at Chicoasén Dam. It's easy to see why this site is the number two tourist attraction in the state of Chiapas.
