The western segment of the Hay-Knapp Creek trail begins near Hindman lake. The trail climbs to a ridge overlooking the lake and the valley below. The climb can be steep in a couple of sections, but is manageable.
Once at the top of the pass, you'll begin with a steep descent on some switchbacks to the creek. Leaving the switchbacks, the trail will mellow out as you drop into flowy singletrack along the creek. There are some rocks to keep you on your toes, and a couple of short ups, but mainly the trail works its way down the drainage at a moderate grade.
At the end of this trail, you'll meet up with the doubletrack road, known as the Hay-Knapp Creek (Western ATV Segment).
