Wallace, ID to Depoe Bay, OR: Road Trip Guide

Wallace, Idaho, sits at the heart of the Silver Valley, a region that once produced more silver than any other in the U.S. . The route to Depoe Bay, Oregon, spans roughly 580 miles, crossing two time zones in just a few hours. You'll climb from 2,700 feet to the 4,300-foot summit of Lookout Pass, then descend into the Columbia River Gorge before meeting the Pacific at Depoe Bay, home to the world's smallest navigable harbor.

This guide covers the essential logistics, natural wonders, and practical tips for making the most of the drive.

Distances are long, but the route is dotted with rest areas every 30-50 miles. Plan to stop every 2 hours to stretch; the best rest areas are at Canyon Ferry (Montana) and Boardman (Oregon). For overnight stays, consider the historic Sacajawea Hotel in Three Forks, Montana, or the Sylvia Beach Hotel in Newport, Oregon.

Fuel and Route Economics

• Gas prices average $3.50/gal in Idaho, $3.70 in Washington, and $3.90 in Oregon; a mid-size car will need about 4 fill-ups.
• The most expensive fuel is often just before entering Oregon, so top up in Washington.

Road Quality and Infrastructure Safety

• I-90 through Idaho and Montana is well-maintained, with occasional construction in summer.
• The Columbia River Gorge section of I-84 is prone to high winds; check wind advisories.
• US-26 between Madras and the coast is two-lane with limited shoulders; use pullouts to let faster traffic pass.
