Horsetail Falls Loop
This loop takes you past three falls and can be accessed either by the Horsetail Falls Trailhead (from which Horsetail Falls is easily visible and accessible) or the Oneonta Gorge Trailhead (just west of Horsetail Falls Trailhead). The hiking directions below start from Oneonta Gorge Trailhead.
From the Oneonta Trailhead, find and follow Gorge Trail #400 (this section of trail #400 is the Historic Columbia River Highway) to the junction with the Horsetail Falls Trail #438. This will lead you first to Ponytail Falls, which you can walk behind. The trail will next take you upward with switchbacks for ~0.5 miles until you reach a bridge over Oneonta Gorge. Oneonta Falls is visible from the bridge, looking downstream. Continuing on, you will reach the junction with Trail #424. To add an extra waterfall to the trip, turn left and hike ~0.9 miles to Triple Falls. To complete the loop, turn right from Trail #438 onto Trail #424. This will lead you back to Oneonta Trailhead where you started.
This hike enters the Mark O. Hatfield Wilderness at approximately a few hundred feet south of the junction of trails #438 and #424. Wilderness restrictions apply. Please note dogs must be on a leash in a wilderness area.
