Sumidero Canyon

Sumidero Canyon is a deep natural canyon located just north of the city of Chiapa de Corzo in the state of Chiapas, in southern Mexico. The canyon's creation began around the same time as the Grand Canyon in the U.S. state of Arizona, by a crack in the area's crust and subsequent erosion by the Grijalva River, which still runs through it. Sumidero Canyon has vertical walls which reach as high as 1,000 metres, with the river turning up to 90 degrees during the 13-kilometre length of the narrow passage.

The canyon is surrounded by the Sumidero Canyon National Park, a federally protected natural area of Mexico which extends for 21,789 hectares over four municipalities of the state of Chiapas. This park is administered by the National Commission of Protected Natural Areas.
