Park Roads

The map below shows the status of park roads and road construction (which occurs every year when weather allows). Click on a road segment or colored icon for more detailed information.

Yellowstone has five entrance stations. 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 mid-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 spring. All dates listed below are subject to change depending on weather and budgetary restrictions.

Conditions in Yellowstone can change quickly, especially during spring and fall. Updates to this map may be delayed, so check back often. Temporary road closures and delays are always possible and may not be shown on this map.
