THIS FACILITY IS CLOSED TO RESERVATIONS UNTIL FURTHER NOTICE Onion Mountain lookout sits atop a 12-foot tower at an elevation of 4,438 feet, offering guests expansive mountain views in southwestern Oregon. The original Onion Mountain Lookout was a raised platform, built on top of a tower in 1916. In 1924, a second lookout without a tower was built on site. The current structure was placed on site in 1952 and served as a fire lookout and Aircraft Warning Service observation station. The lookout offers a unique lodging experience in the Rouge River-Siskiyou National Forest, but visitors are required to bring a few of their own supplies to enjoy a safe and comfortable stay.
