Due to recent snow accumulation and anticipated 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 November 1. During the period of time that the roads remain free of snow, visitors may use the roadways for recreational activities such as walking, bicycling, and in-line skating.
Once snow begins to accumulate on the roadbeds, the status is changed to over-snow access and approved winter season activities such as cross-country skiing, skate skiing, and snow-shoeing become possible. 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 beginning Tuesday, December 4 and continuing through 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.
Grooming is made possible through the financial support of Grand Teton National Park Foundation and its donors with important support from a Federal Highway Administration Recreational Trails Program grant managed by the State of Wyoming.
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.
