Scenic Byway 12
Hell's Backbone, UT

Hell's Backbone road is a dramatic stretch that travels along a ridge with a sheer drop on both sides. Hell's Backbone Bridge spans a crevasse on a narrow ridge no wider than the bridge itself.

Hell's Backbone road starts at Posey Lake Scenic Backway and circles around the rugged Box Death Wilderness Area, ending three miles west of Boulder. Backpacking, camping, hiking, mountain biking, and 4-wheeling are some of the top recreational activities in this area.
