It begins at the parking area and follows Roaring Run for most of its length.
Not far from the trailhead, there is a mandatory hike-a-bike section. Rumor has it that someone once rode it cleanly, but mere mortals need not attempt. If the water is low enough or there is a rock bridge, it's sometimes possible to bypass the hike-a-bike section on the south side of the stream by riding (or hiking) across the stream and following a parallel trail.
About a mile in, the rocks become more sparce and the trail becomes less technical. At about 2 miles from the parking lot, the trail meets up with Sand Spring Trail and the Sand Spring campsite.
