Salem to Hamilton: A Scenic Oregon-Idaho-Montana Road Trip Guide

The route follows I-5 north to I-84 east, then US-20/US-26 through Idaho, and finally US-93 north into Montana's Bitterroot Valley. This 700-mile journey crosses three states and transitions from temperate rainforest to high desert to mountain meadows.
