Recreation areas with activity Backpacking:
From the first access point, below the switchback on Forest Road 5701, the trail parallels the road and passes the ruins of Hickman's Cabin. This moss-covered shelter, built in the 1930s, served as a base camp for fire prevention workers. Continuing, the trail intersects Huffman Peak Trail #129, 0.8 mile from the trailhead. Three creeks are crossed before the trail comes to the second access point, near the end of Forest Road 5701. From here the trail drops steeply to West Creek, where a log bridge spans the stream. Following Siouxon Creek to Horseshoe Creek, you can view Horseshoe Falls from the bridge or take the short 0.1-mile spur trail to get a view of the falls from below.
The main trail then follows Siouxon Creek upstream for 1 mile, offering views of five major waterfalls and their emerald green plunge-pools. After intersecting Horseshoe Ridge Trail #140, the trail continues to the confluence of Siouxon and Wildcat Creeks. Here Wildcat Creek Trail #156 heads north towards Siouxon Peak. A short distance from the junction, the trail again intersects Horseshoe Ridge Trail #140. The trail gains 1900 ft. in elevation in the final 3 miles before ending on Forest Road 58.
