Opening and Closing Schedules
Mother Nature covers Yellowstone National Park in snow during the winter months. Visitors can access the park via car, snowmobile, snowcoach, and cross-country skis. Yellowstone regulates the opening and closing of certain roads for these activities.
The North Entrance to Northeast Entrance at Silver Gate and Cooke City, Montana is open all year.
