Introduction: A Route Across the High Desert
Green River, Wyoming, sits at milepost 89 on I-80, while Baker City, Oregon, is at the base of the Elkhorn Mountains. This 670-mile journey crosses three states and five distinct ecological zones.
The route encompasses the 1805 Lewis and Clark Trail, which passed through what is now Idaho. Travelers today follow US-30 and I-84, a path used by pioneers on the Oregon Trail over 170 years ago.

Fuel, Economics, and Road Conditions
Plan for fuel stops about every 200 miles. Average gas price along the route is $3.50 per gallon; budget $100-120 for the trip. Elevation gain from Green River (6,100 ft) to Baker City (3,400 ft) affects fuel efficiency.
US-30 and I-84 are well-maintained, but winter weather can close mountain passes. Check road conditions before departure via state DOT websites.
- Cheapest fuel: Burley, ID, often $0.20 less than Oregon
- Oregon has no self-service gas stations; attendants pump fuel
- Mountain passes (Cabbage Hill, OR) require chains in winter
Safety, Family Fun, and Rest
Road quality is high, but watch for deer at dawn and dusk. For families, the Idaho Potato Museum in Blackfoot and the Oregon Trail Interpretive Center in Baker City are educational.
Pets are welcome at most rest areas and motels, but keep them leashed.
To avoid fatigue, stop every 2 hours; major rest areas exist near Twin Falls and Ontario. Hidden gems include the Balancing Rock near Arco and the Sumpter Valley Railroad.
