Box Canyon is a Box canyon in Ouray County, Colorado, United States. It was originally founded as a mining camp and helped the city of Ouray establish itself as a permanent community. Box Canyon is home to Box Canyon Falls, a 285 feet (87 m) waterfall, with quartzite walls that extend almost one hundred feet past the falls. Access to the canyon is through a short, 500 feet (150 m) foot trail to the base of the falls or a steep trail leading to the top of the falls.
