This Oregon waterfall loop hits two named falls in 2.5 miles, and neither one charges a parking fee
Most of the big waterfall stops along Highway 126 charge you something these days. Trillium Lake wants $10 to park. Multnomah Falls charges $2 just for the main lot. Sahalie and Koosah Falls, half a mile apart on the same stretch of the McKenzie River, still don’t charge you a dime.

Sahalie Falls plunges 73 feet over a wall of lava rock, close enough that a railing keeps you just twenty feet from the spray. Half a mile downstream, the river drops again at Koosah Falls, a 64-foot curtain landing in a pool blue enough to stop foot traffic at the viewpoint above.
Both falls trace back to the same event. About 3,000 years ago, two lava flows dammed the McKenzie River a mile upstream and formed what’s now Clear Lake — Sahalie and Koosah mark almost exactly where that same lava flow ends and the free-flowing river picks back up.
The trail connecting them is the Waterfalls Loop, a 2.5-mile loop with roughly 367 feet of elevation gain that ties into the longer McKenzie River National Recreation Trail. AllTrails rates it moderate, and most hikers finish the whole loop in under an hour and a half.

If you only have time for one viewpoint, make it Sahalie. The mist reaches the railing on a windy day, and getting a little damp is part of the point.
Both sites have their own parking area, a short paved stretch near the falls, vault toilets, and picnic tables. There’s no potable water at either one, so bring your own.
Go outside summer and check conditions first. The Forest Service doesn’t maintain these parking areas or the trail for snow, and route-finding gets genuinely difficult once everything’s covered.
Sahalie means “heaven” in Chinook Jargon. Koosah means “sky.” Stand at either railing for five minutes and the names stop feeling like a stretch — which one wins the argument for you, the plunge or the pool?
Trip tips: grab a rental car to make the drive out on Highway 126, lock in a hotel in Eugene or Sisters before you go, or turn it into a bigger loop with a camper van instead.
Rules and fees change — always confirm current requirements before you go.
