Coal Creek Trail in eastern Boulder County, stretches, uninterrupted for seven miles along Coal Creek from 96th Street in Louisville to 120th Street in Lafayette.  The 10-foot wide trail is primarily soft-surface, with only a few sections of concrete in low spots.  Also popular among hikers, joggers and stroller-pushing parents, the trail is a quiet place to enjoy nature.  The creek sounds, dense shrubs and canopy of cottonwood trees are a treasure for all.
