The only road generally open year-round to automobiles is from the North Entrance at Gardiner, Montana, through the park to Cooke City, Montana (via Tower Junction). Most park roads are closed to regular vehicles from early November to late-April, and are open to limited oversnow travel (snowmobiles and snowcoaches) from mid-December to mid-March. When open, roads are not gated at night and people may enter/exit the park 24 hours a day, seven days a week.
