OR 46 starts in Cave Junction, at an intersection with U.S. Route 199. It then heads east into the Siskiyou Mountains, terminating at a parking lot for the Oregon Caves National Monument. A forest service road (Grayback Road, NF-4611) splits east from OR 46, eventually reaching the Rogue River Valley and Oregon Route 238.
