Portland to Spokane Road Trip: Scenic Drive Guide

The route from Portland, OR to Spokane, WA follows the historic Columbia River Gorge, a 4,000-foot-deep canyon carved by cataclysmic Ice Age floods. This path, primarily via I-84 E and I-90 E, runs parallel to the Oregon Trail, where wagon ruts are still visible near The Dalles.

Driving this 350-mile stretch takes about 5.5 hours without stops, but the journey rewards those who linger. The question is it worth driving Portland, OR to Spokane, WA? Absolutely, for the dramatic basalt cliffs, vibrant farmlands, and desert palouse.

The gorge can be windy; crosswinds near Hood River affect high-profile vehicles. Winter brings ice on I-84 from Troutdale to Hood River; use chains if needed.

For families, the Oregon Museum of Science and Industry (OMSI) in Portland is a starting point, and the Children's Museum in Spokane is a finish. Pet-friendly stops include Memaloose State Park with river access and the Yakima River Delta walking trail.
