Grass Valley to Sonora: Ultimate Gold Country Road Trip

The route from Grass Valley to Sonora follows Highway 49, California's historic Golden Chain Highway, named for the 49ers who flocked here during the Gold Rush. This 80-mile stretch offers a journey through the heart of the Sierra Nevada foothills, where pine forests give way to oak-studded hills and river canyons.
