The Waldo Mountain fire lookout is located atop Waldo Mountain, in the Willamette National Forest, Oregon.
The original fire lookout tower was built on this site in 1926 and was a small cabin. In 1929 a cupola style lookout replaced the cabin. The current flat top lookout was built in 1956. The lookout is currently unstaffed and no longer a functioning lookout.
This is hike #90 in William Sullivan's 100 Hikes in the Central Oregon Cascades. Sullivan describes the hike as a difficult loop with a 2,000' elevation gain.
