Starting in a fern-filled forest, the trail climbs uphill for 0.6 mile before reaching the top of Coopey Falls, a 150 to 175 foot horsetail waterfall, and the footbridge crossing the creek. Continuing on, the trail begins to switchback uphill for 1.6 miles before reaching the ridge crest. Turn left at a junction to a spectacular gorge viewpoint. Use extreme caution at the steep cliff edge. Continue east 2 miles to Wahkeena Springs and Wahkeena Falls Trail #420. Average trail grade is 10-15%
Attention Hikers: The bridge crossing the Oneonta Gorge on the 438 trail has a ONE PERSON load limit. Please cross with caution and only one at a time. This bridge is 1.3 miles from the Horsetail Falls Trailhead.
The trail begins at Horsetail Falls Trailhead, off the Historic Highway, and ends at Oneonta Trail #424. A fun family hike which takes you behind Ponytail Falls. Steep cliffs at some points.
