From the Scales Horse Corral, this very rocky trail descends towards, and at times seemingly through, Wilson Creek. You can expect to have to watch your footing through this section.
At the bottom, you've got a somewhat challenging crossing of Wilson Creek just before a three-way trail intersection. At the intersection, a left on Seed Orchard Road takes you into Grayson Highlands State Park and a right takes you back to Scales Horse Corral on Wilson Creek Trail. Or turn around and hike this trail uphill for an even bigger challenge.
