Yellowstone National Park
Operating Hours & Seasons

ROAD, SERVICE, & PROGRAM SCHEDULES CAN CHANGE. ALWAYS CHECK LOCALLY FOR UPDATES!

Yellowstone is open every day of the year. Most entrances (except the North and North East entrances) close in November to automobile traffic while roads are being prepared for the winter season's snowcoach and snowmobile traffic and again in late March and early April to clear the roads for the summer season. Interior park roads are only open to over-snow vehicles during the winter season. Once an Entrance/Road opens for the summer season, it is open 24 hours a day. The only exceptions are caused by road construction and weather-related restrictions.

Check News Releases or Current Conditions and Winter Daily Reports for any unscheduled entrance closures due to adverse weather conditions. Throughout the park, in the summer expect traffic delays and road closures. See the Road Construction Schedule for more information.

Please refer to our Opening and Closing Dates for Facilities for information about available services in Yellowstone.
