Sun Valley to Ashland Road Trip: Hidden Gems & Scenic Stops

Starting in Sun Valley, ID (elev. 5,920 ft), you'll traverse US-20 west, then US-95 south, and OR-140 west to Ashland, OR (elev. 1,950 ft). The 480-mile route takes roughly 8.5 hours of pure driving, but plan for 2–3 days to explore. A quirky fact: the tiny town of Jordan Valley, OR, sits atop the Owyhee Plateau and is one of the last places in the lower 48 to have a functioning stagecoach stop from the 1860s.

This route crosses the Snake River Plain, then rises into the Owyhee Uplands and the Fremont-Winema National Forests. The drive is worth it for Crater Lake National Park alone, but the real gems are the lesser-known hot springs and fossil beds.
