Grayson Highlands State Park. Started at Massie Gap, Rhododendron Trail to Horse Trail North. Pass by all the wild ponies. Then, Appalachian Trail Southbound (white blaze) to the side of Wilburn Ridge. Turn left on to Wilburn Ridge Trail (light blue blaze) to the top of Wilburn Ridge. Took Wilburn Ridge Trail all the way back down to the Appalachian Trail. Lots of scrambling on the down.
