Big Horn Mine Trail is a 3.9 mile heavily trafficked out and back trail that features a river and is good for all skill levels. The trail is primarily used for hiking, running, nature trips, and bird watching and is best used from March until October. Dogs are also able to use this trail but must be kept on leash. This is an unmarked trail that can be found below the Mount Baden-Powell/PCT path at the closed road. The trail follows an old mining road all the way to the mine.
