south fork to plane site is a 19.7 mile trail located near Milton-Freewater, OR. The trail is rated as difficult and primarily used for mountain biking.
Great trail, crowded on weekends. Wreckage gone now.
Great trail for hiking, mountain bikes and horses. Only went about 2 miles in as had a pregnant friend with me, but it was a good trail with beautiful scenery and gentle ups and downs. I want to go all the way in sometime. Very popular spot and lots of people on the trail.
