Boulder Ranger District Road Status

Road Openings Delayed

Rain, mud, snowpack runoff and other weather events are causing delays to anticipated road openings. Recent windstorms have led to trees down along many roads and trails. Crews will continue to assess conditions. Challenging obstacles might still exist despite roads being open.
