Only two lookout buildings survive in the Three Sisters Wilderness—the cliff-edge hut at Rebel Rock and the well-preserved, unstaffed building here atop Olallie Mountain. This one has the better view, a panorama of the Three Sisters and eight other snowpeaks. The hike here is easier, too, through beargrass meadows that put on a spectacular summer flower show. And if you’re into exploring, short side trips lead to a secret lake and the site of a former guard station.
