Hike Description

This is a stunning low elevation loop that takes in three waterfalls, looks into the sheer-walled Oneonta Gorge, and offers views over the Oneonta Bottomlands and up the Columbia River Gorge. Families with small children need to be careful at the unprotected cliff viewpoints on Oneonta Bluff and avoid the poison oak that grows along the trail.

The trail begins at one of the most scenic trailheads anywhere, where Horsetail Falls plunges over a basalt cliff. A stone-walled viewing area adds to the ambience. Plan on a bit of time before or after your hike to view and photograph the falls. The Horsetail Falls Trail #438 begins climbing some easily graded switchbacks with beautiful rock walls. You'll pass your first trail junction here, where the Gorge Trail #400 heads east. After five switchbacks, the trail levels out and heads west high above the Gorge below. After 4/10 of a mile, the trail suddenly turns into the small ravine containing Ponytail Falls. (A rooty user trail here leads steeply up to the Rock of Ages Arch.) In literally a few steps, you leave the modern freeway noise and enter a different world. The trail passes behind Ponytail Falls in a cavernous overhang at a soft layer between Columbia River Basalt flows.

The trail continues west, maintaining a level path along the bluff. Rockfall here supports moss, ferns, and a few large maples. A side trail leads to Oneonta Bluff's clifftop viewpoints over the Oneonta Bottomlands below and then east to Beacon Rock and Hamilton Mountain. Directly across the Columbia River is the large forested bowl formed by Indian Mary, Duncan, and Woodward creeks, with Archer Mountain just to the west. Take care and don't step too close to the edge: a plaque memorializes a teen that fell to his death near here. You'll find some camas blooming at the west end of the bluff in spring.

The main trail continues into Oneonta Gorge, where the 2017 Eagle Creek Fire scorched hillsides in a raging canopy fire. Look up the narrow valley and, especially in winter, you'll get some good views of parts of all three lower falls on Oneonta Creek: Oneonta Falls, Middle Oneonta Falls, and the spout of Upper Oneonta Falls in the distance. Just past a weeping wall, the trail begins to switchback down, and you'll get a view into the narrow slot of Oneonta Gorge. A few nails in a tree at the viewpoint are all that remain of the incinerated sign. The trail crosses Oneonta Creek on a metal bridge, which somehow remained unscathed from the Eagle Creek Fire. Just above the bridge is Middle Oneonta Falls, a 15-foot drop. Just below the bridge, the creek disappears over the brink of Oneonta Falls into Oneonta Gorge. The bared slopes above Middle Oneonta Falls bloom with yellow monkey flower in late spring. Beyond the bridge, the trail switchbacks twice up to a junction with the Oneonta Trail #424. (An optional extension up the Oneonta Trail from this junction is the Triple Falls Hike.)

To complete the loop, turn right and head down the Oneonta Trail. The trail crosses a new slide reinforced by a gabion, and then passes above a bench. Phacelia, rosy plectritis, penstemon, alumroot, candy flower, inside-out flower, and columbine bloom along the trail here in spring. Pass over another slide area and below seeping cliffs. Then you'll come to another junction with the #400 trail, this time heading west toward Multnomah Falls. Above the trail junction here, you'll see an old stone wall, and in the winter there's a seasonal waterfall off trail, just above the treeline. Turn right here to stay on the Oneonta Trail, and head down steeply to the Historic Highway, getting views of Archer Mountain across the river.

Turn right and walk half a mile back to your car. You'll walk below basalt cliffs and across the old highway bridge over Oneonta Creek to get a rather limited view up the Oneonta Gorge to the famous "logjam". A couple of interpretive signs tell about the restored Oneonta Tunnel and endemic plants. The 125-foot tunnel through Oneonta Bluff was gutted during the Eagle Creek Fire and was restored in 2020, the previous restoration being completed in 2009. Constructed in 1914, the tunnel operated until 1948 and was then filled with rubble as a newer version of the highway bypassed it. Beyond the tunnel is the small parking area/pullout at the Oneonta Gorge Trailhead.

Take care beyond the tunnel parking lot as the road is quite narrow. A foot trail right next to the highway serves you at first, but check carefully before you cross the bridge over Horsetail Creek to reach Horsetail Falls.
