Rock of Ages - Oneonta Loop(edit)

Overview

The Rock of Ages hike offers a challenging and steep trail with unique viewpoints in the Columbia River Gorge. Starting at Horsetail Falls Trailhead, the trail takes you to three lesser-known viewpoints and provides perspectives of the Rock of Ages and Saint Peter's Dome rock formations. The hike is primitive and not well-maintained, requiring caution in inclement weather.

The trail begins with switchbacks and a bend near the top of Horsetail Falls, leading to the Rock of Ages Trail Junction. From there, hikers climb a steep and slick path, encountering blowdowns and loose rocks. A side path leads to Ponytail Falls, and further uphill is a side trail to the Rock of Ages Arch, offering impressive views. Climbing Devil's Backbone provides more scenic views, including the Horsetail Creek valley and Mount Saint Helens on clear days.

The trail continues along the ridgeline, passing through a serene forest until reaching Horsetail Creek Trail. From there, hikers descend on switchbacks into Oneonta Gorge, crossing Horsetail Creek and reaching the Oneonta Creek Ford. After crossing the creek, hikers join the Oneonta Trail, crossing the creek two more times before reaching a junction with Horsetail Falls Trail. Finally, the trail descends past Triple Falls, Middle Oneonta Falls, and Ponytail Falls, leading back to the starting point at the trailhead.
