Devil's Backbone offers the dramatic hogback rock formations that define Colorado's Front Range—without the crowds you'll find at Boulder's Flatirons or Red Rocks. The tilted rock spine rises sharply from the prairie, creating a striking silhouette visible from Highway 34.
Managed by Larimer County, this 2,200-acre open space connects to adjacent properties for extended hiking options. The trail system is well-maintained with clear signage. It's become a local favorite for residents who want quality hiking close to home.
Trail Options
The Backbone Trail (2.4 miles one-way) follows the base of the rock formation. Moderate difficulty with some rocky sections. This is the main attraction—hiking alongside the dramatic tilted slabs.
Wild Loop (1.4 miles) offers an easier option from the main trailhead. Rolling terrain through grassland with views of the rock formations. Good for families or those wanting a shorter hike.
Keyhole Window requires a short side trip off the main trail. A natural arch in the rock frames views of the plains. Popular photo spot.
Blue Sky Trail connects Devil's Backbone to Horsetooth Mountain Open Space and beyond. Serious hikers can link up 20+ miles of trails. This connector makes Devil's Backbone part of a larger network.
Geological Story
The hogback formation resulted from the same geological forces that created the Flatirons and Red Rocks. Ancient sedimentary layers were tilted nearly vertical as the Rocky Mountains rose. Erosion carved the distinctive spine.
The rock is Dakota Sandstone, the same formation visible across the Front Range. The reddish-brown color comes from iron oxide. Look for fossil ripple marks—evidence this was once a coastal beach.
Interpretive signs along the trail explain the geology and ecology. Worth reading if you're interested in understanding what you're seeing.
