Koosah Falls is a roughly 64-to-74-foot block waterfall on the McKenzie River, the second of three major falls along that stretch in the Willamette National Forest. An easy family loop trail connects it with nearby Sahalie Falls.
Before you go
Waterfalls are hazardous by nature — wet rock, cold water, and unstable edges — and flow varies enormously with season and recent rain. Trail figures here describe the route as documented, not conditions today. Check US Forest Service (Willamette National Forest) for closures and current conditions, and confirm land status before setting out.

Frequently Asked Questions
Koosah Falls drops about 64 feet. That makes it the 348th-tallest documented waterfall in this inventory, taller than roughly 49% of the falls listed here. Height comes from published land-manager and survey records, not from our own measurement.
The Sahalie and Koosah Falls Loop (McKenzie River Trail) reaches it about 2.6 miles (loop), rated easy. The nearest town is McKenzie Bridge. That describes the route as documented, not conditions on the day — check with US Forest Service (Willamette National Forest) for closures and current conditions.
Spring. Waterfall flow swings enormously with snowmelt and recent rain, so a fall that roars in spring can be a trickle by late summer.
