Black Ridge Canyons Wilderness, Protected wilderness area in Mesa County and Grand County, United States.

Black Ridge Canyons Wilderness is a 75,439-acre protected area about 15 miles west of Grand Junction, Colorado, with 5,120 acres in Utah. Seven major canyon systems cut the east-west Black Ridge, draining into the Colorado River in Ruby Canyon. Canyons reach almost 1,000 feet deep in red rock cliffs, with spires, windows, giant alcoves and desert varnish; elevations run from 4,700 to 6,800 feet.

The U.S. Congress designated the Black Ridge Canyons Wilderness in 2000, protecting 75,439 acres, of which 70,319 lie in Colorado and 5,120 in Utah. The Bureau of Land Management administers it as the core of the 123,430-acre McInnis Canyons National Conservation Area.

The name Rattlesnake Canyon comes from the snakes found there, and the canyon holds nine natural arches, the second-largest concentration in the United States after Arches National Park. The area is managed by the Bureau of Land Management, and visitors can hike up canyons such as Rattlesnake, Moore, Mee and Knowles from the Colorado River.

The wilderness can be accessed from three main entry points, each offering different terrain and experiences. Visitors should research which access point best matches their interests and hiking ability before planning their visit.

Rattlesnake Canyon holds the second-largest concentration of natural arches in the United States, after Arches National Park; the French source counts nine arches in all. The arches sit in the high country reached from Glade Park, Colorado, not from the Fruita side.
