West Yellowstone to Jackpot: An Epic Road Trip Guide

This 300-mile journey from West Yellowstone, Montana to Jackpot, Nevada traces the path of the 1877 Nez Perce War, when Chief Joseph led his people across what is now the Beartooth Highway and along the Continental Divide, dodging U.S. cavalry. You'll traverse three states—Montana, Idaho, and Nevada—and transition from the snowy peaks of Yellowstone National Park's northern gateway to the high desert sagebrush near the Nevada-Idaho border. The route primarily follows US-20, I-15, and US-93, crossing the Continental Divide at 7,100 feet near Monida Pass, a key geological and historical threshold.

Driving time is about 5.5 hours without stops, but with attractions like the Continental Divide, Craters of the Moon National Monument, and the Snake River Plain, you'll likely double that. This guide covers every aspect of the trip—from fuel stops and weather to family-friendly activities and hidden gems—ensuring you know what to expect and where to go. Whether you're heading for Jackpot's casinos or making a scenic detour, here's everything you need.

Note that this route is not a major interstate corridor, so services are spaced out—plan fuel and food stops carefully.

Check road alerts for mountain passes, especially in winter, as sections can close unexpectedly due to snow.

Road quality is high, but watch for livestock and deer, particularly at dawn and dusk, and in winter, carry chains or snow tires. The route includes long stretches of two-lane highway, so be patient and pass with care.

• Rest areas are sparse; plan breaks in Idaho Falls or Arco.
• Families: Craters of the Moon and the Museum of Idaho in Idaho Falls offer educational stops.
