Columbia Falls to Kemmerer: A Montana-Wyoming Road Guide

Drive U.S. Route 89 south from Columbia Falls, Montana, and you'll immediately notice the dramatic change from the Flathead Valley's rainy timberline to the sun-baked basalt of Yellowstone's northern plateau. The road passes through the heart of the Northern Rockies, crossing the Continental Divide at 5,910 feet, before descending into the high desert of Wyoming. This 820-mile journey takes about 12.5 hours of pure driving, but plan for at least 3 days to savor the landscape.

The route is bookended by two very different towns: Columbia Falls, a lumber town turned outdoor recreation hub, and Kemmerer, a former coal mining company town. Between them lie national parks, ghost towns, and geothermal wonders. Here's how to make the most of this scenic transcontinental drive.

Yellowstone National Park is the crown jewel, spanning 3,472 square miles with geysers, hot springs, and the Grand Canyon of the Yellowstone. Nearby, Grand Teton National Park offers 200 miles of hiking trails with views of jagged peaks. Continue south to Fossil Butte National Monument, where 50-million-year-old fish fossils are embedded in limestone.

Local commerce thrives on tourism and agriculture. Columbia Falls' historic downtown has a co-op and breweries. In Kemmerer, visit the J.C. Penney Mother Store, the original 1902 dry goods store that spawned the retail chain. The route passes through the Wind River Indian Reservation, where you can buy authentic beadwork and bison jerky at roadside stands.

UNESCO World Heritage Sites along this drive: Yellowstone is one of the few sites listed for its geology, and nearby Waterton-Glacier International Peace Park (a short sidetrip from Columbia Falls) was designated in 1995. Both are accessible from the route.

Wildlife collisions are a risk, especially at dawn. In Yellowstone, speed limits are 45 mph capped to protect animals and drivers. Winterize your vehicle if driving between October and April—chains may be required on Teton Pass (elevation 8,431 feet).

Family-friendly stops include the Grizzly & Wolf Discovery Center in West Yellowstone and the National Museum of Wildlife Art in Jackson. Pets are welcome in many campgrounds but not on park trails; board them at kennels in West Yellowstone. For kids, the Yellowstone Historic Center has hands-on exhibits.

Rest zones: every 100 miles, take a 15-minute break. Key spots include Ennis Lake (mile 220), Henrys Lake State Park (mile 300), and the Bear River State Park (mile 780). Caffeine and stretching reduce fatigue; avoid driving more than 8 hours a day.

Hidden off-route spots: Chico Hot Springs near Livingston offers soaking pools since 1900. The Teapot Dome gas station in Rock Springs is a kitschy photo stop. At Fossil Butte, the visitor center shows a film on the fossil lake, but the real gem is the .9-mile Nature Trail.

U.S. 89 runs nearly the entire route, but you'll also use Interstates 90 and 80 between segments. The road quality is generally good, with asphalt in good condition, though winter weather can close passes like Teton Pass. Cell service is spotty, especially in Yellowstone, so download offline maps.
