Black Canyon of the Gunnison National Park is one of Colorado’s last hidden gems. The national park sits outside Montrose, Colorado, in the lesser-known southwestern corner of the state. The five-hour drive from Denver deters most tourists, who head to Rocky Mountain National Park instead — a park that saw4.2 million visitorsin 2022, while Black Canyon had just 297,257. Moreover, the park boasts natural wonders that can wow even the most skeptical. The park is marked by2,700-foot cliffsthat plunge to the Gunnison River, as well as hiking trails that wind along the canyon rim.
