Winter Trip Planner
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.
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 the Cross-country Skiing & Snowshoeing brochure (Adobe PDF), visit 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/snowshoe trail brochure.
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.
