Yellowstone National Park’s winter season begins Monday, Dec. 15. Annually from mid-December until mid-March, visitors can travel most of the park’s roads from the West, South, East and North entrances by approved commercially guided snowmobiles and snowcoaches and via the non-commercially guided snowmobile access program.
Currently, the accumulation of snowfall on roads varies across the park. This means that visitors will be able to travel in the park, however, the type of transportation used on park roads by commercially guided snowmobile or snowcoach tour companies will depend on road conditions. Throughout the winter season, park staff will work closely with all operators and provide updates as conditions change.
Winter travel ends in mid-March when plowing crews begin to clear a winter’s worth of snow. Roads will start to re-open to automobiles beginning in mid-April.
Top Things to Know in Winter
Most Park Roads are Closed to Automobiles
The only roads open year-round are between the North Entrance in Gardiner, Montana, and the Northeast Entrance in Cooke City/Silver Gate, Montana (via Mammoth Hot Springs, Tower Junction and Lamar Valley). Anticipate possible road closures due to quickly changing weather and dangerous driving conditions. Check the
road status map before you arrive. Drive cautiously and give plenty of space to snowplows. Do not stop, stand, or walk in the road. Use a turnout if you need to stop for any reason.
Want to See Old Faithful?
Park partners, concessioners and authorized businesses offer a variety of guided tours throughout the park during the winter months.
Services are Limited
Most facilities are closed during winter. Check
winter operating dates to see which visitor centers, stores, restaurants, lodges and warming huts are open.
Camping and Lodging
Old Faithful Snow Lodge and Mammoth Hot Springs Hotel are open during winter. Make reservations as far in advance as possible. Lodging is also available in nearby communities. There is limited first-come, first-served camping available at the Mammoth Campground.
Prepare for Winter Conditions
Winter temperatures range from zero to 20°F (-20°C to -5°C) throughout the day. Sub-zero temperatures are common, especially at night and at higher elevations. Check current weather conditions, pack proper clothing and equipment and review
winter safety tips.
Do Not Approach or Feed Wildlife
Animals have the right of way. Expect to encounter bison and other wildlife on park roads. Slow down or pull over until they pass or move off the road. Stay 100 yards (91 m) from bears, wolves, and cougars and 25 yards (23 m) from all other wildlife. The safest way to view wildlife is through a telephoto lens, a spotting scope or a pair of binoculars. Store food properly and be aware that in some areas, ravens have learned to unzip backpacks to obtain contents.
Stay on Boardwalks
People have been severely injured or killed by breaking through thin ground in thermal basins or falling into hot springs. Exercise caution and wear traction aids over footwear when navigating snowy or icy boardwalks.
