Winter in Grand Teton


Winter is a wonderful time to experience Grand Teton National Park. As the snow drapes a wintry blanket across the Teton Range, a peace settles over the landscape offering a sharp contrast to the busy summer season. Winter recreation activities abound, as the park becomes a popular destination for cross-country skiers, snowshoers, and photographers who wish to capture the beauty of a Teton winterscape. If you are planning a visit during the winter season, make sure you check current weather forecasts and road conditions to ensure a safe and enjoyable trip.


Road Information

Winter driving may be challenging; park roads are often covered with ice or hard-packed snow; winter storms create white-out driving conditions. Make sure your vehicle is equipped with winter or all-season tires and carry tire chains when driving over mountain passes. For updated road information in the park call: 307-739-3682. For Wyoming Department of Transportation information, visit their website: or call 1-888-WYO-ROAD (only available in Wyoming) or 307-772-0824 or 511 on your cell phone.

The park's main roadways, Highway US 89/191 and Highway US 26/287, are plowed and open for winter travel from the town of Jackson to Flagg Ranch just south of Yellowstone National Park. These travel routes offer outstanding mountain vistas and wildlife viewing opportunities. Park roads are often snow-covered and icy. Be prepared for winter driving conditions and carry a winter safety kit in your vehicle for emergencies. In addition, wildlife can linger near park roads, so be alert, and drive slowly for their safety and yours.

Much of the Teton Park Road (also called the inner park road) is closed to vehicles during winter. The unplowed section of the road from Taggart Lake Trailhead parking area to Signal Mountain Lodge-a distance of 15 miles-is open to non-motorized use only (skiers and snowshoers). A variety of other trails throughout the park offer winter visitors many ways to experience a snowy Teton wonderland. As a safety precaution, outdoor enthusiasts should carry-at a minimum-water, high energy snacks and extra winter clothing during any backcountry excursion. Please see our Cross-country Skiing & Snowshoeing web page or stop by the Jackson Hole and Greater Yellowstone Visitor Center in Jackson, Wyoming to speak with a park representative about suggested trails and safety tips, or to pick up a ski and snowshoe information.

Teton Park Road (Taggart Lake Trailhead to Signal Mountain Lodge): closed to vehicles, open to skiing and snowshoeing access.

Highway 26/89/191 (outer park road): open year-round from Jackson to Flagg Ranch or Togwotee Pass and Dubois, WY.

Weather and Avalanche Information

Winters are long and cold in Jackson Hole. The first heavy snows fall by November 1 and continue through April; snow and frost are possible any month.

If you are planning to travel in the backcountry during the winter, be sure to check the local avalanche forecast. Avoid known avalanche paths. All skiers and climbers travelling in avalanche terrain should be equipped with, and know how to use, an avalanche beacon, probe pole and shovel. For current conditions call 307-733-2664 for the U.S. Forest Service avalanche report or go to:

Hypothermia is caused by exposure to cold and is aggravated by wind, exhaustion and wet clothing. Warning signs include: uncontrollable shivering, incoherent speech, lethargy and exhaustion. Remove the victim from the elements as soon as possible. If in doubt, seek immediate medical attention.

Ranger-guided Snowshoe Walks

A snowshoe walk with a park naturalist is the perfect way to introduce yourself to winter in the Tetons and to experience the fun of traveling on snowshoes. Naturalists provide guided snowshoe walks from the Taggart Lake Trailhead when snow conditions permit, usually the day after Christmas to mid-March.

Snowshoes are available for a rental fee of $5 for adults and $2 for children, 8 years or older. More>>

Safety in the Backcountry
Hikers and climbers are reminded that your safety is your responsibility. You must rely on your own good judgment, adequate preparation and constant awareness. Backcountry users should be in good physical condition and stick to routes that are within your ability and comfort levels. Hypothermia and frostbite can set in quickly, and are difficult to care for while in the backcountry. Take preventative measures to avoid the dangers of cold weather; look for signs of hypothermia and frostbite in members of your group. Traveling alone can be especially dangerous; always give friends or family a detailed itinerary and stick to that plan. Permits are required for all overnight backcountry trips, are free of charge and available at the administration building at park headquarters in Moose Monday through Friday 8:00 am-4:30 pm. On weekends and federal holidays, persons wanting a backcountry permit should call park dispatch at 307-739-3301. Watch our video podcast for more information about winter safety.

Cross-country Skiing & Snowshoeing
Cross-country skiing and snowshoeing are two of the best ways to experience the exhilaration of winter travel. Winter is an excellent time to see wildlife and/or signs of wildlife in the snow. From November 1 to May 1, the Teton Park Road from the Taggart Lake Trailhead to Signal Mountain Lodge is open for non-motorized use only. You can ski or snowshoe on this road, which is intermittently groomed to provide a packed surface for snowshoeing and crosscountry touring. Other places to enjoy cross-country skiing and snowshoeing include Colter Bay, Antelope Flats Road, Taggart Lake and Flagg Ranch. If you plan to ski or snowshoe the Moose-Wilson Road, park at the Granite Canyon Trailhead or at the junction to the Death Canyon Road.
