We started at Fish Creek TH (west terminus. There is an outhouse here, not sure if it was open), and had lunch at Indian Henry Campground (closed, but plenty picnic tables. The trail is somewhat rocky, recommend ankle support. Well placed rocks, wood planks, one serious bridge to cross a creek. Only one short muddy section. A few down trees. Overall the trail is in great shape. Since it's close to the road, car noise is unavoidable. Pup Creek falls is a delight, covered with ice. It's a 0.2 mile detour to see the falls. Well worth it. Most people would turn around here, and midway point of the trail.
East of here has The Narrow, which is the prettiest spot on the river. Don't know why there's a rope hanging in the middle.
Part of the trail is in a wilderness. A few big trees.
We met at most 10 hikers. Heard gunshots.
