JACKSON, Wyo. — Travel on the majority of the Teton Park Road, Moose-Wilson Road, and Signal Mountain Summit Road within Grand Teton National Park is now open to over-snow access only­. The designated portions of these roads now accommodate winter recreation while the use of wheeled vehicles is prohibited for the season.

Once snow begins to accumulate on the roadbeds, the status is changed to over-snow access and approved winter activities such as cross-country skiing, skate skiing, and snowshoeing become possible. Bicycles, including, snow/fat/electric bikes, are not permitted on roads designated for over-snow access. Bikes are allowed on 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 three times a week dependent on snow and weather conditions.

  • Tuesdays- Four lanes groomed Taggart to South Jenny Lake
  • Fridays- Two lanes groomed Taggart to Signal Mountain
  • Sundays- Four lanes groomed Taggart to South Jenny Lake

Grooming is anticipated to begin soon and will continue through mid-March, as conditions allow. Grooming is made possible through the financial support of Grand Teton National Park Foundation and a Federal Highway Administration Recreational Trails Program grant managed by the State of Wyoming.  For grooming updates, call the park’s road information line at 307-739-3682.

Parking will be modified this winter to help facilitate snow plowing activities and additional parking for day-use, backcountry and Teton Park Road recreationists. Parking will be allowed at Taggart Lake Trailhead and on the west side of the road south of the trailhead. New this winter, parking will also be available north of Taggart at the Cottonwood Creek Picnic Area and along the west side of the road across from the picnic area. Backcountry-users who plan to stay in the backcountry overnight are encouraged to use the Taggart Lake Trailhead parking, while day-users are encouraged to park along the west side of the road and at the Cottonwood Creek Picnic Area. Porta potties will be available.

Visitors planning to recreate on the northern portion of the Teton Park Road for winter activities are encouraged to park at the Signal Mountain Lodge Parking Area.  The lodge provides restroom facilities, telephone access and pay-at-the-pump gasoline for winter recreationists.

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. Pets are not allowed in the backcountry.  For the safety of wildlife, pets and visitors, pets must be leashed at all times. Pet owners are required to pick up waste.  Dog sledding and ski joring are not allowed in the park.
