I was lucky to hike this trail twice within three weeks from the confluence with Quartz Creek to Lower Falls. Pics from the second trip are at the Flickr link below, including a bit of Quartz Creek Trail, Curly Creek Falls Spur, and Lewis R. Trail from Curly Creek to Bolt Camp.
Rainy woods filled with vanilla leaf and inside-out lilies in mid-June gave gentle way to sun-dappled woods filled with red huckleberries as well as almost-blue ones. Maidenhair, deer, lady and sword ferns as well as many mosses and thriving fir, Douglas and Bigleaf maple, cedar, alder, and hemlock were profuse and verdant both times. In mid-June, I also hiked below the campground, across FR 90 and a few miles along the trail. There were a couple of trees down on this section, all small and easy to get over, as well as one small stream too wide to jump but not over boot depth if you chose your spot (we removed boots because it felt so good to wade).
There are some steep or eroded sections on the viewpoint to above Upper Falls, and a few sections along the Lewis R. Trail could use brushing and tread widening where maple or berry bushes push hikers to the outside of the trail. These are still fairly minor issues. The main obstacle is the trail to Middle Falls is closed from the bridge below the falls (which appears to be fine, but a logical place to close it) to the upper section joining the main trail where a washout appears pretty irreparable. It looks like the Forest Service has flagged the reroute through the woods. In the meantime, hikers need to use the Middle Falls trailhead/parking area to go around the closed part of the trail.
This trail is popular with hikers and bicyclists alike. On this sunny holiday weekend, both the campground and almost all the backcountry camps along the river were full by Friday. We also saw two kayakers just above Taitnapum Falls but didn’t have the time or nerve to run to the viewpoint that would have allowed us to see them go over. We’re going to assume they made it safely. :)
