Open Space and Mountain Parks
Boulder's Open Space & Mountain Parks are a very special place. The lands teem with native plants and wildlife and are home to threatened and endangered species. They serve as a buffer between Boulder and nearby development. They sustain agriculture uses and add untold benefits to the natural environment - clean air, water, and earth.
The lands shape the urban mosaic of the Boulder Valley and provide citizens with passive recreation opportunities. Trails are used by walkers, hikers, bicyclists, horseback riders, dog walkers and other passive recreational uses.
