Starting from the Old Rag Mountain Fee & Information Station, we'll walk the Weakly Hollow Fire Road to the Robertson Mountain Trail. We'll then have a steep climb to the summit of Robertson Mountain with excellent views of Old Rag and Corbin Hollow. After descending from the summit, we'll have an easy and gentle hike back to our cars on the Old Rag Fire Road and Weakly Hollow Fire Road. Total elevation gain for hike: 2,900 ft.
