Oregon Caves National Monument & Preserve is in the Siskiyou Mountains, 20 miles east of Cave Junction on SR 46 (Caves Highway).

Due to narrow roads and ice and snow concerns, drivers of trailers and large recreational vehicles are discouraged from traveling the Caves Highway but can park at the visitor center in Cave Junction and drive smaller tow vehicles to the caves.
