Astoria to Columbia Falls Road Trip Guide: Oregon to Montana

This route covers approximately 700 miles from Astoria, Oregon, at the mouth of the Columbia River, to Columbia Falls, Montana, just outside Glacier National Park. It's a drive that transitions from coastal rainforests to high desert, then into the Rocky Mountains.

The route primarily follows US Highway 30, Interstate 84, Interstate 82, Interstate 90, and US Highway 2. Total driving time without stops is about 11 to 12 hours, but you'll want to stretch it over several days to explore.

One little-known fact: the stretch of US Highway 2 in Montana follows the historic Marias Pass, the lowest crossing of the Continental Divide in the northern Rockies, discovered by the Great Northern Railway in 1889.

The Columbia River Gorge offers dramatic waterfalls and windsurfing. Farther east, the landscape turns arid near The Dalles. In Washington, the Palouse region's rolling hills are photogenic. As you approach Montana, the Flathead Valley leads into Glacier National Park.

UNESCO World Heritage Sites: none directly on route, but nearby are the Frank Lloyd Wright's Taliesin West (in Scottsdale, AZ) and Yellowstone National Park (south of Montana). However, the route passes near the Nez Perce National Historical Park (NPS), which is affiliated.
