Blue Sky Trail

The Blue Sky Trail, connecting the Devil's Backbone Open Space to Horsetooth Mountain Open Space along the Front Range mountain backdrop, has been on Larimer County's wish list for over ten years. Traversing through 4,000 acres of protected foothills open space is one of the premiere regional trails in Northern Colorado for hiking, biking, and horseback riding and crosses only one road over the total 15-mile distance. The land acquisitions to allow this project to occur have been planned and orchestrated over a 7-year period, with trail segments built in stages following land acquisition. The final stage in making this regional trail system a reality was completing the last 8.5 miles of natural surface trail and an associated underpass near Horsetooth Reservoir.
