This area consists of roads that start in the sagebrush flats and climb among the pine, fir, and aspen. Choose a variety of road surfaces from maintained graveled to undeveloped two-tracks. Some private land is on the mountain so ask permission before riding off of public roads. Also, there may be active logging operations on the mountain so be alert for equipment and logging trucks. A variety of rides can be found from a 31-mile loop ride based out of Prior Flat Campground (no water available) to shorter rides on the mountain. Trips can last one hour to all day. Wildlife viewing includes deer, elk and pronghorn.
