Hike Description

Lava issuing from the Sand Mountain area poured down the McKenzie River valley about 3,000 years ago in two separate flows, creating the benches over which two large waterfalls, Sahalie Falls and Koosah Falls thunder. Interpretive signs at the Sahalie Falls Trailhead considerably exaggerate the height of both falls at 120 feet and 90 feet respectively. In fact, both have similar drops of about 75 feet, but remain impressive nonetheless. The Waterfalls Loop Trail takes you to both waterfalls and then connects with the McKenzie River National Recreation Trail on the west bank for a quiet return away from the crowds. Some of the most rewarding sections of this hike are along ice-blue sections of the McKenzie, where tumbling cascades drop through a dark and mossy forest corridor.

Take the paved trail leading down from the right side of the parking area. Make a left and then a right down a flight of steps. You’ll arrive at a viewpoint to Sahalie Falls, formerly known as Upper Falls, where it pours over a lava ledge from a constricted defile (sahalie is the Chinook Jargon word for ‘high’). At times of high water, a second stream of water drops from a lava bowl to the right of the main flow.

Continue on the Waterfalls Loop Trail downriver. A series of steps takes you close to the McKenzie where it tumbles in a sequence of picturesque cascades. A green canopy of Douglas-fir, western hemlock, and western red-cedar towers overhead. The river continues to pours through a constricted channel before making a fifteen-foot drop over a minor waterfall. You’ll reach a bench and railed viewpoint which offers a partial view of Koosah Falls, formerly Middle Falls (koosah means ‘sky’). These falls offer different profiles at different times of the year. In the driest months, there are two separate streams of water dropping into a large amphitheater, while at full spate the waterfall appears as a single 70-foot wide plunge. Part of the McKenzie’s flow finds passage under the lava, and it issues forth here as a series of springs at the base of the waterfall.

At a fork on the trail, go right (left will take you up to the Koosah Falls Trailhead). Pass another viewpoint now obscured by vegetation, and keep right again. Narrow steps lead down to the best viewpoint of Koosah Falls, a head-on vista up the canyon where you can make out a rock pinnacle on the forested slope above the falls. The river narrows under lava cliffs. Keep right at another junction, and descend to reach a one-lane bridge over the McKenzie at the Carmen Reservoir, a diversion facility for the Eugene Water and Electric Board (EWEB). Take the road over the bridge, and pass an information kiosk. When you reach a vault toilet at the Carmen Reservoir Trailhead, look right where the loop trail reenters the forest.

Hike up to the McKenzie River-Waterfalls Loop Trail South Junction, and make a right at an impressive Douglas-fir. As the trail twists up through mossy lava outcroppings, look left for a massive log nursing a flock of baby hemlocks. Arrive at a viewpoint to Koosah Falls – take care here: the viewpoints on this side don’t have protective railings! The river narrows, and a spur trail leads to the McKenzie’s bank and a great view of the unnamed falls above Koosah. Next a scramble trail from a switchback leads out to a vista over Sahalie Falls’ amphitheater. There’s another view of Sahalie Falls from the main trail higher up, and you’ll soon pass near the lip of this thundering plunge.

The next spur switchbacks down to dark swirling, bubbling pool on the McKenzie. The river’s ravine narrows, and the trail crosses an exposed lava flow populated by vine maples. Above a log jam, the McKenzie is a quieter, broader river and the River Trail crosses a substantial footbridge to reach the McKenzie River-Waterfalls Loop Trail North Junction. The old single log footbridge lies nearby. Make a right on the Waterfalls Loop to pass mossy boulders on a lava ridge. An old access road runs nearby. At a junction, you can go right for a close view to the top of Sahalie Falls. Next, keep left to reach the parking area.
