Yellowstone National Park 2018-2019 Winter Season Started December 15

Delayed opening between North Entrance and Swan Lake Flat for snowmobiles

At 8 a.m. Saturday, December 15, select roads in Yellowstone National Park were opened to the public for motorized oversnow travel. Winter is here!

Visitors will be able to travel the park’s interior roads on commercially-guided snowmobiles and snowcoaches from the North, West, and South Entrances. Visitors who have proper permits can also participate in the non-commercially guided snowmobile trips. More on the Non-Commercially Guided Snowmobile Access Program.

Travel between the North Entrance and Swan Lake Flat will be limited to commercially-guided snowcoaches. This section will remain closed to visitor snowmobile use until more snow accumulates on the road. Plan accordingly and stay informed. Travel from the park’s East Entrance over Sylvan Pass is scheduled to begin Friday, December 22, weather dependent.

The road from the park’s North Entrance at Gardiner, Montana, through Mammoth Hot Springs to Cooke City, Montana, is open to wheeled vehicle travel all year.
