Gore Canyon is a short isolated canyon on the upper Colorado River in southwestern Grand County, Colorado in the United States. The steep and rugged canyon, approximately 3 miles (5 km) long, was carved by the river as it passed the northern end of the Gore Range southwest of Kremmling. The Colorado descends from approximately 7300 ft to approximately 7000 ft over the length of the canyon. The steep walls ascend approximately 1000 ft on either side.
