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.
