Mammoth Hot Springs, Wyoming – Beginning Nov. 1, Yellowstone National Park will close the majority of its internal road network and three of its main entrances – the West, South and East – to regular vehicle traffic. The seasonal shutdown is part of the park’s preparation for winter operations and the opening of the snowmobile and snowcoach travel season on Dec. 15.
Roads and entrances affected
All internal thoroughfares, except for the route that links the North Entrance in Gardiner, Montana, to the Northeast Entrance at Cooke City and Silver Gate, Montana, will be closed to standard vehicles. The remaining open corridor runs through Mammoth Hot Springs, Tower Junction and the Lamar Valley and will stay accessible year‑round, weather permitting.
Exceptions and limited access
The only road that will stay open beyond the general closure date is the stretch connecting Tower Fall to Canyon Junction over Dunraven Pass. This segment is scheduled to remain usable through Oct. 31, provided weather conditions allow safe travel.
Visitor guidance
Park officials advise anyone planning a late‑fall or winter visit to be flexible with travel plans and to monitor changing weather conditions. Updated travel restrictions and road status reports are available on the official Park Roads webpage. For real‑time alerts, visitors can call 307‑344‑2117 for recorded updates or text “82190” to 888‑777 to receive mobile phone notifications.
Why the closures matter
Closing the majority of roads helps protect the park’s fragile winter ecosystem, reduces the risk of accidents on snow‑covered routes, and allows the National Park Service to focus resources on winter‑specific operations such as snowmobile and snowcoach tours, wildlife monitoring, and snow removal. The limited north‑to‑northeast corridor provides a safe passage for essential staff, emergency responders, and winter‑season tourists.
Planning your trip
Travelers should consider alternative routes if they intend to enter the park from the West, South or East entrances after Nov. 1. The North Entrance in Gardiner remains the primary gateway for winter access, and the park’s official website offers detailed maps and seasonal travel tips. Visitors are also reminded that winter weather in Yellowstone can be severe and change rapidly, so packing appropriate gear and checking forecasts before departure is essential.
Stay informed
The National Park Service encourages all guests to stay informed through the park’s communication channels. By using the phone line, text alerts, or the online road status page, visitors can receive the latest information on road conditions, closures, and any temporary re‑openings that may occur due to weather improvements.
