It is bordered on the west by Sonora, on the north by the United States (New Mexico and Texas), to the east by Coahuila, to the southwest by Sinaloa, Durango to the south.

The state is occupied by a desert plateau that slopes sharply toward the west. This mountain is also the largest tourist attraction of the state, the picturesque Barranca del Cobre ( " Copper Canyon "). The north of the state is the Chihuahuan Desert, which also occupies the neighboring state of Coahuila almost completely and parts of the southern United States.
