With a snowy fall having laid down a reasonable snowpack on Yellowstone National Park, the park will open for the winter season on Sunday.

Beginning at 7 a.m. Sunday, visitors will be able to travel to the park’s interior roads on commercially guided snowmobiles or snowcoaches from the North, West and South entrances. Travel through the park’s East Entrance over Sylvan Pass is scheduled to begin December 22.

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

At Old Faithful, the Geyser Grill, the Bear Den Gift Shop, and the Old Faithful Visitor Education Center open for the season on December 15. The Old Faithful Snow Lodge and Cabins and the Obsidian Dining Room open on December 18.

The Mammoth Hot Springs Hotel, dining room and gift shop will open for the season on December 20. The Yellowstone General Store, the medical clinic, campground, post office and the Albright Visitor Center at Mammoth Hot Springs are open all year, as are the 24-hour gasoline pumps at Mammoth Hot Springs and Tower Junction.

Park staff members will continue to closely monitor road conditions and weather forecasts that can have an impact on roadways and guided oversnow travel operations. Weather during the winter season is extremely unpredictable in Yellowstone and road closures or delays can occur with little or no warning. Visitors are reminded to come prepared by carrying personal emergency survival equipment in their vehicles and dressing appropriately for outside activities in extremely cold weather.
