Eldorado Canyon to Walker Ranch Connection

A group of three local and state governments have proposed a preliminary interagency recommendation for a multi-use trail connection between Eldorado Canyon State Park and Walker Ranch. After collaboration to complete a Trail Feasibility Study and careful consideration of the findings, Boulder County Parks & Open Space, the City of Boulder Open Space and Mountain Parks, and Colorado Parks and Wildlife are jointly recommending the North Route (using segments N1-N2-N4) as the preferred alignment for an Eldorado Canyon to Walker Ranch multi-use trail connection. Please visit the project website to learn more.
