The Coal Creek Regional Trail is a 14-mile of soft-surface trail that parallels Coal Creek, from South 66th Street in Superior through Louisville and Lafayette to Vista Parkway in Erie. 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.
