Yellowstone National Park, Grand Teton National Park & Region
The road between Mammoth Hot Springs and Old Faithful, as well as the road between Norris and Canyon, is open once more!
The road between the North Entrance (outside Gardiner) and the Northeast Entrance (serving Silver Gate and Cooke City) remains open all year.
The Importance of Knowing Yellowstone Road Conditions
Navigating Yellowstone National Park is both simple and complicated. It’s simple in one sense in that the main road, the Grand Loop, provides access to all services inside the Park, and the simplicity of the road plan makes it highly unlike you’ll get lost. On the other hand, given the long stretches of road between services, you’ll want to plan ahead, as it takes some time to get around (the posted speed limit is 45 MPH, and that limit is certainly enforced by Park officials), which makes a knowledge of Yellowstone road conditions so important. At this time of year only part of the Park is open to road traffic, while plows groom the roads in the rest of the Park for snow coaches and snowmobiles in coming weeks.
