Hike Description

Announcement: Join Trailkeepers of Oregon (TKO) as part of a volunteer trail crew on the Oneonta Trail on Tuesday, June 28th, 2016. Sign up here!

This hike is a grueling climb to the top of Larch Mountain and it's not even the shortest route. It passes several interesting waterfalls and a beautiful section of creek. Later, it climbs like the dickens through forests and open rock slopes. You'll visit low level old growth and higher level old growth hemlock forests. At the top, you'll have a wonderful view of 5 snowclad mountains.

Oneonta Trail #424 starts climbing gently to a junction with Gorge Trail #400. The trail climbs to a shelf above the Columbia River where a side trail leads to viewpoints. Continuing on, the trail clings to the side of Oneonta Canyon, high above hidden Oneonta Gorge below. Soon, there's a junction with Horsetail Falls Trail #438. Then there's a quiet, unimproved trail down the hill to Oneonta Falls. Triple Falls comes next, followed by a bridge over Oneonta Creek. The trail then follows the east side of the creek to another bridge over Oneonta Creek. There's another trail junction, this time with Horsetail Creek Trail #425.

After this last trail junction, the trail begins climbing in earnest. In the next mile and a half, the trail gains about 2000 feet to a ridge crest. From here to Larch Mountain Road, there is a complex network of trails. All of the junctions are detailed in the trail log. At mile 8.3, the trail comes to Larch Mountain Road at the Upper Oneonta Trailhead. If you want to go to Larch Mountain Trailhead, turn right and walk up the hill 0.3 miles.
