Cody, WY to Leavenworth, WA: Ultimate Road Trip Guide

The road from Cody, Wyoming to Leavenworth, Washington traverses the rugged spine of the Rockies, the volcanic landscapes of Idaho, and the apple orchards of central Washington. This 800-mile journey on US-20, I-15, and I-90 (among others) typically takes 13-14 hours of pure driving, but to properly experience its wonders, plan for 2-3 days.

A little-known fact: the route crosses the Continental Divide three times, climbing over 8,000 feet at Togwotee Pass near Jackson Hole. The stark transition from the high plains to the Pacific watershed is a geological drama that unfolds over 1,200 kilometers.

The primary highways are US-20 West out of Cody through Shoshone National Forest, then I-15 North near Idaho Falls, followed by I-90 West from Butte, Montana into Washington. Other key roads include US-26 (briefly) and WA-970 to Leavenworth.

Gas stations are abundant in towns but sparse on remote stretches like that between Dubois and Jackson, WY (80 miles without services). Idaho Falls and Butte are major refueling hubs. Prices tend to be lower in Montana and Idaho by about $0.10-$0.20 per gallon compared to Wyoming and Washington.

Best Stops Cody, WY to Leavenworth, WA

• Shoshone National Forest: North America's first national forest, with the winding North Fork Highway and dramatic Absaroka Range views.
• Togwotee Pass: A high alpine crossing (9,658 ft) that offers panoramic vistas of the Teton Wilderness.
• Grand Teton National Park: Briefly accessible via US-89/191; plan a detour for exquisite mountain scenery.
• Idaho Falls: Located on the Snake River, with a charming riverwalk and greenbelt perfect for a leg-stretching stop.
• Craters of the Moon National Monument: An otherworldly volcanic landscape near Arco, ID (off I-15 but worth a 30-mile detour).
• Butte, MT: A historic copper mining city; the Berkeley Pit overlook offers a glimpse into industrial history.
• Spokane, WA: A vibrant city with Riverfront Park and the Spokane Falls; ideal for an overnight rest.
• Leavenworth, WA: A Bavarian-themed village nestled in the Cascade foothills, known for its alpine architecture and festivals.

Road quality is generally excellent: interstates are well-maintained, but secondary roads like US-20 can be narrow with sharp curves. Winter conditions from October to April may require chains or all-wheel drive, especially over Togwotee Pass and Lookout Pass on I-90. Summer brings construction zones; check 511 for updates.

For families, the route offers kid-friendly attractions: the Buffalo Bill Center of the West in Cody, the Moose Visitor Center in Grand Teton, and the interactive exhibits at the Idaho Museum of Natural History in Pocatello. The Leavenworth Nutcracker Museum is a quirky stop for all ages.

Pet-friendly amenities are decent: most motel chains (La Quinta, Motel 6) accept pets, and many national forest campgrounds allow dogs on leash. Rest areas along I-90 and I-15 have designated pet exercise areas. Carry water and bowls as remote stretches have limited services.

To manage fatigue, plan a stop every 2-3 hours. Optimal rest zones include the town of Jackson, WY (mile 130), Idaho Falls (mile 290), Butte, MT (mile 500), and Spokane (mile 680). These offer reliable food, lodging, and services. Avoid driving late at night on unfamiliar mountain roads; wildlife (deer, elk, moose) crossing is common at dusk.

The route is a survey of America's western geography: from the volcanic peaks of the Yellowstone Plateau to the sagebrush steppes of the Snake River Plain, then the rugged Clearwater Mountains of Idaho and the apple orchards of the Columbia Basin. The final approach to Leavenworth winds through the Wenatchee National Forest, with the Cascade Range providing a dramatic backdrop.

Beyond the national parks, hidden gems include the ghost town of Kirwin, WY (accessible via unpaved roads near Meeteetse) and the Gold Rush-era town of Warren, ID, deep in the Payette National Forest. These off-road spots require a high-clearance vehicle and a sense of adventure.

Local commerce along the route is a mix of standard chain motels and independent cafes. In smaller towns like Dubois, WY, you'll find rustic diners serving buffalo burgers and huckleberry pie. Idaho Falls offers a diverse food scene with Basque influences. As you approach Washington, fruit stands selling apples and cherries become common in season (July-October).
