Onion Mountain Lookout

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.

Public land it sits in

On Wilderness Atlas →

This campground sits inside Rogue River-Siskiyou National Forests.

Each unit is published as a centre point and an acreage rather than a boundary, so this section stands it in for a circle of the same area. Whether a campground is inside, and how far it is from one it is outside, are both approximate.
