Portland to Salmon Road Trip Guide: Hidden Gems

This route traces the historic Oregon Trail but with modern twists: you'll cross the Continental Divide at Lost Trail Pass (elevation 7,014 ft), where the landscape shifts from rainforests to sagebrush steppe. The drive spans 485 miles and takes about 9 hours without stops, but plan for 10-12 hours to savor the sights. Key highways: I-84 E from Portland to Boise, then US-20 E and ID-28 N through the Salmon River Valley. A local quirk: many gas stations in Idaho close by 8 PM, so fill up early.
