From Grants Pass, OR, go south on Highway 199 (Redwood Highway) 18 miles to Selma, OR. Turn right at the Post Office (yellow flashing light) on to County Road 5070 (Illinois River Road) which becomes Forest Road 4103. The road is paved only short distance past Store Gulch. The remainder of the road is gravel / dirt often with pot holes. The last few miles get more narrow and rugged and high clearance vehicles are suggested. The road ends at the trailhead. There are some junctions to private property in the Oak Flat area. At the junction with Forest Road 4105, stay to the left on 4103.
