Google Maps will give you excellent directions to Elk City and Dixie. For those without smart phones the following directions will get you to Elk City. Take US-95 to Grangeville. Turn on to Main Street, ID-13 and drive through town. On the east edge of town you will reach the junction of ID-13 and the Mt. Idaho Grade Road. Turn south (right) onto the Mt. Idaho Grade Road. The road takes a sharp left turn in 0.7 miles and continues through a few houses (aka Mt. Idaho). Soon thereafter the road begins a long, steep descent into the South Fork of the Clearwater River canyon. At the bottom the road meets ID-14. Turn left and follow the road for 38 miles to the Red River Road, FS-222. Go left at this junction to visit Elk City or go right for 14.0 miles to reach the Red River Ranger Station. The Magruder Corridor starts just south of the Ranger Station. Dixie is 15.0 miles further south on FS-222.
