Yellowstone seasonal road closures
The majority of the park’s roads are open until Nov. 5, when they’re closed in preparation for the winter season. After that date, only the year-round North Entrance Road from Gardiner to Cooke City, through Mammoth Hot Springs, will remain open to auto travel, weather permitting.
The road from Tower Junction to a barricade just north of the Chittenden Road turnoff on Dunraven Pass closed for the season on Sept. 22 for construction. Visitors will be able to access Chittenden Road and the Mount Washburn area from Canyon Village to the south, until that section of road closes for the season on Oct. 9.
Outside the park, the high-altitude section of the Beartooth Highway (Highway 212) between the junction of Highway 296 and Red Lodge can close unexpectedly depending upon snowfall. The highway officially closes for the season Oct. 9, and travel between Red Lodge and the park’s northeast entrance isn’t possible until it reopens in late May.
Fall weather is unpredictable, and roads may be closed temporarily by snow or other weather conditions with little or no warning. Updated information on park roads is available 24 hours a day by calling (307) 344-2117. Outside the park, you can check Wyoming roads by calling (888) WYO-ROAD or by visiting wyo.road.info, or Montana roads at (800) 226-7623 or mdt.mt.gov/travinfo.
All lodging and most visitor centers in the park will be closed by the end of October. By the first week of November, most campgrounds will be closed for the season. The Mammoth Hot Springs campground is the only site that remains open all year.
Limited lodging and services will available again when the winter season begins in mid-December. 24-hour pay at the pump fuel remains available at all service stations year-round.
