During a recent drive along the McKenzie River Highway, we stopped at both Sahalie and Koosah Falls to stretch our legs and take photographs. Of the two falls, Sahalie Falls is the most popular stopping point for travelers. This 73 foot tall waterfall is near the head of the McKenzie River (which originates at Clear Lake just a couple miles upstream), and you can hear the thundering water as you get out of your car in the nearby parking lot.
Koosah Falls, just half a mile downstream from Sahalie Falls, receives fewer visitors and has a significantly smaller parking lot. Koosah plunges 64 feet into a large pool. Water levels were low when we visited; during higher volume times the water will spread along the whole ledge. Both waterfalls are along the McKenzie River Trail (a 26 mile hiking and biking trail) and a short trail connects the two.
The waterfalls are 90 miles northeast of Cottage Grove on Highway 126 (the McKenzie River Highway).
