This hike starts on the road for a little less than a mile before reaching the trailhead, the path is rocky at the bottom and becomes a series of scrambles after several miles. The views are amazing, the entire hike was really pleasant, and it was quite windy and beautiful at the top. My 11 year old joined me and had no trouble at all, he is an avid hiker and loves rock scrambles. It will be a few years before I take my younger children. Parking is $15 for a week, or use tour national park pass. No camping in the parking area or at the higher elevations on Old Rag (basically when it becomes really rocky). Parking area has trash and porta-potties.
