This strenuous loop follows Madison Run Road, an abandoned mountain road through the valley of Madison Run, before ascending to Austin Mountain. Begin by following the Austin Mountain Trail off the parkway, then make a left on Madison Run Road. After a series of switchbacks into the valley, the trail follows the edge of the creek and offers idyllic and seldom-disturbed gullies. Turn right onto Austin Mountain Trail and begin following the spine of the mountain up to the rocky summit. After passing numerous fascinating geological formations unique to the Blue Ridge Mountains, come to the summit of Austin Mountain and catch a gorgeous look at Trayfoot Mountain in the distance. As the loop nears its close, the trail will intersect with the Rockytop Trail briefly before veering right back to the parking area.
