Yellowstone has five entrance stations, the North Entrance, Northeast Entrance, East Entrance, South Entrance and the West Entrance. It takes many hours to drive between these entrances, so be sure to check the status of roads at the entrance you intend to use. Most park roads are closed to regular vehicles from early November to late-April (see dates below) when the park switches to oversnow travel (snowmobiles and snowcoaches). The only road open year-round is from the North Entrance at Gardiner, Montana, through the park to Cooke City, Montana (via Tower Junction). Travel east of Cooke City (via the Beartooth Highway) is not possible from late fall to late May.
On Oct. 15 Tower Fall to Canyon (Dunraven Pass) and Beartooth Highway (US 212 to Red Lodge, Montana) were closed. On Nov. 4 all other Yellowstone roads will close at 8 a.m. except the road between the North Entrance and the Northeast Entrance.
