Canon del Sumidero above the Grijalva River

Canon del Sumidero near Chiapa de Corzo drops into a limestone gorge carved by the Grijalva River, with walls rising over 1,000 m.

Canon del Sumidero is a limestone gorge just north of Chiapa de Corzo in Chiapas, Mexico. Its steep walls rise above the Grijalva River, giving the landscape a vertical scale that is visible from the river and from the rim.

Canon del Sumidero’s limestone walls and river course

The canyon belongs to the Parque Nacional Cañón del Sumidero, which was declared a national park on 8 December 1980 and later recognised as a Ramsar wetland site. Those designations place the gorge within a protected landscape shaped by water, rock and deep relief.national parkRamsar wetland site

The walls rise to more than 1,000 m, and their limestone and basaltic faces dominate the river corridor. Geological descriptions place the canyon within the Chiapas Depression, where the Grijalva has cut through faulted terrain and exposed layers of older rock.limestone and basaltic faces

Chiapa de Corzo and the Grijalva corridor

Chiapa de Corzo sits at the southern end of the gorge, where the river enters the canyon. The place is tied to the Grijalva channel, the nearby capital Tuxtla Gutiérrez, and the broader lowland-to-upland transition of Chiapas.Chiapa de Corzo

Ramsar documentation places the park across several municipalities, including Chiapa de Corzo, Tuxtla Gutiérrez, San Fernando, Osumacinta, Chicoasén, Soyaló and Ixtapa. That broad footprint helps explain why the canyon belongs to both a river landscape and a wider protected basin.several municipalities

A protected gorge with wildlife and rock

The park holds a mix of riparian habitat, steep cliff vegetation and rocky slopes, with endemic and protected species recorded in official descriptions. The same documents also note cave paintings and archaeological remains in the area, linking the gorge to long human occupation.protected species

For a visitor, the strongest impression is the scale of the walls against the river’s narrow course. The canyon is not a built monument but a natural corridor, with rock, water and height working together as the main features of the place.
