Operating Hours & Seasons
Yellowstone is always open but it's a little complicated so read on.
The road between the north and northeast entrances is open to automobiles year-round. This road provides access to Mammoth Hot Springs, the park's wildlife-rich northern range (including Lamar Valley), and activities like cross-country skiing, hiking, camping, fishing, and wildlife-watching. Other park roads are open during summer, but have closures and travel restrictions during the shoulder seasons and winter. Please see the following pages for more information:
