Why go
River-level views and land-based lookouts reveal different aspects of the canyon’s scale. The Grijalva bends through steep walls, while viewpoints such as El Roblar look across a landscape with marked elevation changes. Rain brings waterfall activity, but the narrow channel and Chicoasén Dam also help explain why floating waste can accumulate here.
What to look for
- El Roblar is one of the canyon’s named land-based viewpoints.
- The Chicoasén Dam lies at the canyon’s northern end.
The full story
The canyon was shaped by fractures in the earth’s crust and erosion by the Grijalva River. Its walls and sharp river bends are part of a connected water landscape, extending upstream beyond the protected area and downstream to the Chicoasén Dam. The reservoir changes how water and material move through the northern end of the canyon. That connection matters when looking at the scenery. Waste arriving from upstream can become trapped by the narrow passage, converging currents and backed-up water. Conservation therefore involves more than the cliffs immediately around a boat or lookout. The surrounding vegetation also changes with relief: deciduous forest predominates, with smaller areas of pine and oak. Seasonal rainfall feeds features such as the Árbol de Navidad waterfall, adding another layer to a landscape whose appearance depends on water as well as rock.
Useful to know
- Decide between a river outing and land-based lookouts; they offer different perspectives on the canyon.
