The 12-mile Rock Creek Regional Trail is primarily a soft-surface trail that parallels Rock Creek from Superior, through Carolyn Holmberg Preserve at Rock Creek Farm to the Rock Creek and Coal Creek Confluence in Lafayette. For locals, the trail offers access to nature just steps from home while it also provides a corridor for wildlife.

Starting in 1990, the Coal Creek and Rock Creek Trails project is the product of an area-wide partnership. Boulder County, the Town of Superior, the cities of Louisville and Lafayette, and the Urban Drainage and Flood Control District, all worked and will continue to work together to ensure the trail’s completion.
