Many of Grand Teton National Park’s roads and services close in the winter, creating a wonderful sense of solitude you will not find in the summer season. However, the park’s main roads Hwy 89/191 and Hwy. 26/287 are plowed all winter and are open to cars from Jackson, Wyo., north to Flagg Ranch, which is just two miles south of Yellowstone National Park’s South Entrance. It’s $20 to enter the park on skis and $35 to enter in your vehicle.
To get there, fly into the Jackson Hole Airport, which is seven miles from town and located in Grand Teton National Park. It’s the only airport in the country completely located in a national park. It’s serviced by American, Delta, United and SkyWest. You can rent a car on site or take a taxi or the Jackson Hole Shuttle.
Granite Canyon Entrance
This entrance is accessed by the Moose-Wilson Road in Wilson, Wyo., which passes the Jackson Hole Mountain Resort before reaching the park. The Moose-Wilson Road is closed to vehicular traffic beyond the Granite Canyon trailhead in the winter, so if you want to snowshoe or ski on the road, park at the trailhead parking area.
The park’s Moose Entrance is open to vehicular traffic only to the Taggart Lake Trailhead. From Taggart Lake trailhead, you can skate ski, cross-country ski or snowshoe a gorgeous 15-mile snow-packed surface that is intermittently groomed all the way to Signal Mountain Lodge. With the majestic Tetons towering above, skiing or snowshoeing here will be one of the most memorable experiences in your life.
Thirty miles north of Jackson you’ll find the Moran Entrance. It’s less popular than the Moose Entrance because it’s farther from Jackson but offers opportunities for winter enthusiasts to snowshoe or cross-country ski. You also can access the Teton Park Road groomed trail by snowshoe or skis from here.
