Yellowstone has five entrance stations. Make sure to carefully read about access at each station at different times of year.
During the late spring, summer, and fall (year-round for the North-Northeast entrances) park entrances and roads are open 24 hours for entry, exit, and travel. Please remember to travel at or below the posted speed limit when driving Yellowstone roads from dusk until early morning due to the possibility of encountering wildlife along park roadways.

November through April, the North Entrance provides the only access to Cooke City, MT. US Highway 212 east of Cooke City is closed to wheeled vehicles November through April. The road from Mammoth to Norris opens to wheeled vehicles in late April through early November, and to tracked-oversnow vehicles, conditions permitting, from mid December to early March.
