Visitors are allowed to snowshoe and do cross-country skiing and are not restricted to trails.
The Teton Park Road between the Taggart Lake trailhead to Signal Mountain Campground is closed to vehicular traffic during the winter and this section of the road is groomed for skiing and snowshoeing traffic.
The park service offers guided snowshoe tours daily from the main headquarters located in Moose, Wyoming.
Overnight camping is allowed in the winter in the backcountry with a permit and visitors should inquire about avalanche dangers.

The only location in Grand Teton National Park where snowmobiles are permitted is on Jackson Lake.
The National Park Service requires that all snowmobiles use "Best Available Technology" (BAT) and lists various models of snowmobiles that are permitted, all of which are deemed to provide the least amount of air pollution and maximize noise abatement.
All snowmobiles must be less than 10 years old and have odometer readings of less than 6,000 mi (9,700 km).
Additionally, snowmobile use is for the purposes of accessing ice fishing locations only.
Snowmobile access was permitted between Moran Junction and Flagg Ranch adjacent to the John D. Rockefeller, Jr. Memorial Parkway so that travelers using the Continental Divide Snowmobile Trail could traverse between Bridger-Teton National Forest and Yellowstone National Park.
However, in 2009, winter use planners closed this since unguided snowmobile access into Yellowstone National Park was also discontinued.
