Park routes

Three bison linger on a plowed area of Antelope Flats Road, in Grand Teton National Park, Wyo., in early February. 

Due to recent snowfall, the status of Teton Park Road, Moose-Wilson Road, and Signal Mountain Summit Road within Grand Teton National Park has been changed from wheeled access to over-snow access.

The designated portions of these roads are now ready to accommodate winter recreation and use of the roads by wheeled vehicles is prohibited for the season.

Each year, Teton Park, Moose-Wilson and Signal Mountain Summit roads are closed to public motor vehicle use beginning Nov. 1. 

Once snow begins to accumulate on the roads, the status is changed to over-snow access and approved winter season activities such as cross-country skiing, skate skiing, and snow-shoeing. Snow bikes are not permitted on roads designated for over-snow access. Snow bikes are allowed on all roadways open to motor vehicle use in Grand Teton National Park.

The 14-mile section of the Teton Park Road between the Taggart Lake Trailhead and Signal Mountain Lodge will be groomed approximately twice-weekly from late-December to mid-March. The road is scheduled to be groomed on Tuesday and Friday mornings, though the schedule is dependent on snow and weather conditions. For grooming updates, visitors can call the park's road information line at 307-739-3682.

New this year, a webcam will show the condition of the groomed road and prevailing weather conditions from the Cottonwood Creek Bridge in real time. A link to the webcam will be posted on the park's website at as well as the park's social media channels once the solar-powered camera is up and running.

Generally, pets are only permitted along park roadways open to motor vehicle use. However, pets are allowed on the over-snow access portions of the Teton Park Road and Moose-Wilson Road by special exception. For the safety of wildlife, pets, and visitors in wildlife habitat, pets must be leashed at all times. Pet owners are required to pick up waste.

Grand Teton National Park will continue to maintain safe access on other park roads, including US Highway 26/89/191, during the winter season.
