Twin Falls to Coos Bay Road Trip: Desert to Coast

The drive from Twin Falls, Idaho to Coos Bay, Oregon is a 580-mile journey that crosses the Snake River Plain, the high desert of eastern Oregon, the Cascade Range, and the lush coastal forests of the Oregon Coast. The route largely follows US-20/US-26 west, then OR-42 southwest. One surprising fact: near the midpoint, you'll pass through the town of Burns, Oregon, which is one of the few places in the US where the highway is lined with wild mustangs roaming freely—a living remnant of the region's ranching history.
