Black Canyon of the Gunnison National Park
The Gunnison River cuts an exceptionally narrow, deep gorge through ancient rock, producing abrupt light, scale, and exposed rim terrain. Use several short rim overlooks before a longer trail; each reveals different relationships among river, wall, and narrowest points.

Black Canyon of the Gunnison National Park is a national park of the United States located in western Colorado and managed by the National Park Service. The Black Canyon of the Gunnison was established as a national monument on March 2, 1933. It was redesignated a national park on October 21, 1999, and incorporated 4,000 acres owned by the Bureau of Land Management.
Look for pale pegmatite dikes crossing dark gneiss and schist—the canyon’s geology is visually legible from the rim. Rely on several short rim overlooks before a longer trail; each reveals different relationships among river, wall, and narrowest points.
