Small Canyon southwest of the city of Durango where the Chico and Los Arcos rivers meet.

The canyon is framed by a wooded vegetation of pines and oaks and the Tunal River flows through its bottom. 

Several movies have been filmed in this place and you can practice various ecotourism activities. There are interpretive trails with signs about the tree species.

There is a camping area with toilets, palapas and grills.
