The Dalles to Columbia Falls: Scenic Road Trip Guide

Begin in The Dalles, where the Columbia River narrows into a swift gorge, a natural chokepoint that Native Americans used for salmon fishing and Lewis and Clark noted in 1805. Today, Interstate 84 runs east along this ancient waterway, then climbs into the sagebrush plains of Eastern Oregon before crossing into Idaho and Montana.

The trip spans approximately 600 miles, and the fastest route is I-84 east to I-82 north, then I-90 east to US-93 north to Columbia Falls. With ideal conditions, you can complete the drive in 10 to 11 hours, but plan for a full day to appreciate the scenery.

Your drive follows well-maintained interstates and highways, with the only mountain pass being Lookout Pass on I-90, topping out at 4,725 feet. Fuel prices along the route are generally lower in Idaho than in Oregon or Montana, averaging $3.25 per gallon as of mid-2024.

• I-84 through Oregon: Radar-enforced speed limits, 70 mph.
• I-90 in Montana: Long stretches, 80 mph speed limit.
• US-93 north: Winding, watch for wildlife.

Rest areas are plentiful, but the longest gaps are between Boise and Ontario (60 miles) and Missoula to Columbia Falls (no services for 30 miles). Plan fuel and rest accordingly.

Family-friendly: The Oregon Trail Interpretive Center in Baker City offers interactive exhibits; in Montana, the Conrad Mansion in Kalispell provides a historic tour.

Pet-friendly: Most rest areas have designated off-leash zones, and many hotels along I-90 allow pets for an extra fee. Carry water for pets, as summer temps can exceed 90°F.

For fatigue, make a point to stop every two hours; the Port of Wilbur rest area on I-90 has scenic views.

Hidden detour: The Gem State's how to find the best stops and hidden gems between cities suggests checking out Skalkaho Pass, a gravel road that's a slower but breathtaking alternative between Missoula and Hamilton.

The route transitions from the arid Columbia Plateau to the pine-clad Rockies. Notable geologic feature: the Palouse Falls in Washington, a short detour, is a 200-foot waterfall that cascades into a crescent-shaped canyon.

Historic Nez Perce lands in Idaho offer cultural heritage sites like the Nez Perce National Historical Park, which includes over 38 locations. Visit the visitor center in Spalding to understand the tribe's history.

For local flavor, stop at a family-run wheat farm near Pendleton, Oregon, or a huckleberry stand in Montana.
