Discover what season is best for you by reviewing the seasonal highlights, then check the schedule to see when roads open and close. Yellowstone has five entrance stations, and several are closed to regular vehicles during winter. It takes many hours to drive between entrances, so be sure to check the status of roads at the entrance you intend to use. The road between Mammoth Hot Springs and the Northeast Entrance is always open to regular traffic, providing year-round access to the wildlife-rich Lamar Valley and great access for camping, hiking, fishing, or skiing. Below you’ll find details about the facilities and services available. For winter times, check out the Explore in Winter page.
