Victor to Yakima Road Trip Guide: Scenic Drive through Idaho & Washington

At mile 0 of US-20 east, the Teton Range looms behind your rearview mirror. This road trip from Victor, Idaho to Yakima, Washington traverses the Snake River Plain, the Sawtooth foothills, and the Columbia Basin — a 450-mile journey that climbs from 6,200 feet to 1,100 feet.

The quickest route is via US-20 West to I-84 West and I-82 West, taking roughly 7 hours without stops. But the real reward lies in the detours: the million-year-old lava flows of Craters of the Moon, the cultural crossroads of Shoshone Falls, and the wine-soaked hills of Prosser.

For those wondering how long to drive Victor, ID to Yakima, WA, plan 7–9 hours of wheel time, but we recommend a full day or two to savor the sweep from the Tetons to the Cascades.
