Boulder Ranger District Road Status

Forest Roads Status - Home

Roads listed as "Open" or "Closed" are open during summer/fall and closed during winter/spring. Closures can occur during summer if unforeseen changes in conditions occur. Depending upon road conditions, gates east of the Peak-to-Peak Highway open sometime in May, while gates west of the Peak-to-Peak Highway open in June or later. National Forest system roads are not listed in this table do not have a seasonal gate. These routes are not maintained for 2WD passenger vehicles and may not be passable.

ALERT: It is not always possible to post road closures or openings on the day that they occur. Call 303-541-2500 to confirm road status before heading up to your destination. Closed areas are open to foot traffic unless otherwise noted.

The Motor Vehicle Use Map will help ensure that you are on a road authorized for public use. The map is free, differentiates National Forest from other lands, and illustrates where camping is allowed. Motor Vehicle Use Maps are available online and at district offices.
