This non-motorized trail is the original Twelvemile Forest Service trail. It is five miles of pure fun for the expert mtn biker. There will be short hike a bike for some bikers. There are numerous stream crossings, some with logs. Expect to get your feet wet. Early in the season, the water is high and cold. June-October is best. The trail is not well marked in places but the old Forest Service blazes are there. Lower down you will pass a cabin site from the Uncle Sam Mine, which was operational before 1927.
