About Koosah Falls
Koosah Falls (also called Middle Falls) tumbles along the McKenzie River in the heart of the Willamette National Forest in Linn County, Oregon. The second of the three major McKenzie River waterfalls, Koosah sends a dramatic main drop of about 64 feet (roughly 20 m) into a deep pool and is often cited as about 70 feet from rim to plunge. The falls sit just south of Santiam Pass and roughly 0.5 miles downstream from Sahalie Falls, framed by lush Cascade forest and volcanic rock that make it a favorite stop for photographers and day hikers alike. The site and trail access are managed by the U.S. Forest Service. A short USFS spur (WATERFALLS, Trail #3503) leads to the primary viewpoints, and many visitors link Koosah with Sahalie for a popular loop. The combined route is about 2.6 miles with roughly 200 feet of elevation gain and is generally rated easy, offering an accessible outing through classic McKenzie River scenery in the Willamette National Forest.
