About the Hike
Yamsay Mountain is a large, gently sloping shield volcano that is hard to notice at first. It ranks 73 on Oregon's list of 100 highest peaks, coming in at 8,196 feet in elevation. The hike is long and passes through coniferous forest, but the summit is very prominent and offers views from the Three Sisters to Mount Shasta.
History of the Area
The name is derived from a Klamath word for the north wind. The summit, where a crater was carved by an Ice Age glacier, used to have a fire lookout that was dismantled.
The trailhead for Yamsay Mountain is located 90 miles south of Bend and 75 miles north of Klamath Falls.
1. Take Highway 97 to the Silver Lake and Highway 76 junction, and turn east.
2. Pass by the Klamath Forest National Wildlife Refuge and turn onto Forest Service Road 49, which is between mileposts 21 and 22. A sign for Jackson Creek campground is also located at the turnoff.
4. Continue for 1.4 miles and make a left turn onto FR 4973, marked “Marsh View Trail” and “Yamsay Mountain.”
5. Pass the “Short Cut Trail” on the right about 0.1 mile into FR 4973, until the road reaches a fork going straight ahead or hard right; bear to the right. At this point the road becomes overgrown on the sides and can potentially scratch the sides of wider vehicles.
6. Continue on this road for a few additional miles before reaching the trailhead, where there should be room for several vehicles to park.
