Heading south from Joe Graham Horse Camp, just below Timothy Lake, this stretch of the Pacific Crest Trail runs to the Willamette National Forest boundary in the Mount Jefferson Wilderness. The north trailhead is at Joe Graham Campground on Skyline Road (Forest Road 42), reached from US Hwy 26.

After a long run through varied terrain, it reaches the Olallie Lake Scenic Area, follows the west side of Olallie Butte to Olallie Lake, and goes by Upper Lake on the way to Forest Road 4220. Olallie Lake and that road both make good starting points. South of the road it climbs into rocky alpine country with snow, where the tread is hard to find, so watch for small cairns.
