Bears are active in Grand Teton

Black and grizzly bears are roaming throughout the park even in most winter months—near roads, trails, and in backcountry areas. Hikers and backcountry users are advised to travel in groups of three or more, make noise, and carry bear spray. Visitors must stay 100 yards from bears. For more information on bears checkout out Safety in Bear Country.

Temporary Area Closures are in Effect

There are temporary area closures in effect at locations throughout the park. These closures protect wildlife and visitor safety. For additional information and maps of each individual closure see Temporary Closures and Compendium Amendments.

Winter 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.
