Canon del Sumidero, the sheer gorge above the Grijalva
Published on 09/10/2026 at 15:30 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
Canon del Sumidero in Chiapas is a river gorge where the Grijalva cuts through near-vertical cliffs, forming a national park landscape that feels carved on a monumental scale. North of Chiapa de Corzo in southern Mexico, the canyon walls climb hundreds of metres above the water and give the protected area its defining drama.
River, rock and height in Canon del Sumidero
Canon del Sumidero is a deep canyon created by the Grijalva River as it flows through the state of Chiapas in southern Mexico. The gorge lies just north of the colonial town of Chiapa de Corzo and close to the larger city of Tuxtla Gutiérrez, making it one of the most accessible stretches of wild river scenery in the region.deep natural canyon The cliffs form an imposing corridor of rock that rises high above the river, with some walls reaching around 1,000 m (3,281 ft) from the waterline to the rim.cliffs up to a kilometre high
The Grijalva riverbed in Canon del Sumidero is framed by steep rock faces, patches of vegetation and occasional small beaches or rock ledges. In places the gorge narrows to a tight passage, while in others it opens to wider reaches where the water feels more expansive beneath the walls. The river continues northwards towards the reservoir held back by the Chicoasén hydroelectric dam, a major engineering project of the late twentieth century that created a long lake at the upper end of the canyon.Chicoasén hydroelectric dam
Canon del Sumidero as a national park
The gorge and the surrounding hills form the core of Sumidero Canyon National Park, a protected area recognised in Mexico for both its ecological and scenic value. The park covers tens of thousands of hectares in several municipalities of Chiapas, with Canon del Sumidero as its central feature.Sumidero Canyon National Park The national park was established in 1980, giving formal protection to the canyon landscape and its wildlife at a time when conservation areas were being defined across Mexico.established in 1980
Within the park, Canon del Sumidero is known for a mixture of steep cliffs, forested slopes and river habitats. Crocodiles and river turtles are reported along the Grijalva, and birds can be seen crossing between the walls or perching on ledges above the water.crocodiles and river turtles The protected status aims to keep the canyon’s geology, vegetation and fauna intact around the existing boat route, road access and viewpoints. From the rim, several named miradores look down into the gorge, each giving a different angle on the river and the surrounding terrain.
Experiencing Canon del Sumidero from Chiapa de Corzo
For visitors based in Chiapa de Corzo, Canon del Sumidero is most directly experienced from the water itself. Standard boat trips leave from embarkation points near the town and run along a narrow section of the gorge beneath sheer cliffs, waterfalls and the feature known as the “Christmas Tree”, where mineral-rich water has built up a curtain of mossy rock over time.standard approach - a fast open boat The journey typically covers a stretch of around 13 km (8.1 mi) through Canon del Sumidero before reaching the broader waters of the reservoir.
On land, a road from Tuxtla Gutiérrez climbs to viewpoints along the rim, allowing a contrasting way of seeing the canyon from above rather than along the waterline.rim viewpoints by road From these miradores the height of the cliffs and the tightness of the gorge become more obvious, with the Grijalva appearing as a thin ribbon far below. The combination of boat route and viewpoints means Canon del Sumidero can be understood both as a corridor of moving water and as a fissure cut into the plateau.
