From the base of Upper Sunset Wall, one can hike and scramble to the left of the cliffs and then above them, after which it is a short distance to the crags directly beneath the summit of Old Rag (they come into view once you reach this small pillar called Old Rag Gendarme, which has a bolted line on it).
