The trail guide says this is a two-day backpack, but we did it in three days with a patrol of young Boy Scouts. It was a pretty good climb from Goat Creek up to Tumwater Mountain, where we spent our first night. We were very happy to find water in the pond atop the mountain. Then it was a simple ridge walk to Deadmans Lake for the second night. Wildflowers abundant in the few places where the trail took us out of the forest. Easy hike out from Deadmans Lake through some impressive old-growth forest back to the trailhead.
