Winthrop to Helena Road Trip: Scenic Guide

This route from Winthrop, WA to Helena, MT is a 500-mile journey that transitions from the arid, pine-dotted Methow Valley to the granite peaks of the Rockies. The drive takes approximately 8 hours without stops, but you'll want to linger. A quirky fact: just east of the Washington-Idaho border, Highway 20 crosses the Pend Oreille River at the exact spot where the 1910 Great Fire stopped—a turning point in forest fire management.
