Oneonta Trail #424 reaches the falls about 1.7 miles from the Oneonta trailhead. Plan on roughly 3.2 to 3.6 miles round trip, depending on the route, and about 1,100 feet of climbing. The trail climbs above the Historic Columbia River Highway, then follows Oneonta Creek through the upper canyon. You get open views across the Columbia River and toward the mouth of Oneonta Gorge before a short side path drops to the falls. From that clifftop, frame all three channels with the bridge just above them; that's the signature view.
