Boulder Ranger District Road Status

Roads listed as "Open" or "Closed" are open during summer/fall and closed during winter/spring. Closures can occur during summer if unforseen 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. Most national forest system roads are not listed in this table because they do not have a seasonal gate. Most of these routes are not maintained for 2WD passenger vehicles and may not be passable.

PLEASE NOTE: 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.

The Motor Vehicle Use Map will help ensure that you are on a road authorized for public use while on the forest and grassland.  The map is free, district specific and available both electronically or at district offices.
