Rimrock Open Space
Rimrock Open Space is an important component of Larimer County's Front Range Mountain Backdrop and continues the protection of significant aesthetic and ecological values. The unmarred view of imposing red rock cliffs rising against a mottled background of mountain mahogany shrubland is a striking western landscape that is rapidly disappearing as residential development creeps into the Larimer County foothills. From incursions by native peoples, to settlement by homesteaders, to the influence of quarries and an encroaching community, this area has seen a great deal of change over time. The Larimer County Open Lands Program purchased the 472-acre Rimrock Open Space in partnership with the City of Fort Collins.
Currently access to Rimrock Open Space is accomplished through the Coyote Ridge Natural Area off County Road 19, midway between Fort Collins and Loveland. Here hikers, mountain bike enthusiasts, and equestrians may traverse a seven mile round-trip trail and enjoy a spectacular viewshed of dramatic red rock cliffs and hogback valleys. In the summer of 2006, the Rimrock Open Space trail system became part of the Blue Sky Trail extending from the Devil's Backbone trailhead to Horsetooth Reservoir.
