It starts from the concrete slab bridge (at V984847), and follows a worn track southwards up to the Devil's Punchbowl at 670 meters , before reaching the Mangerton summit plateau via the west ridge of the Punchbowl, and then walking circa 300 metres across the plateau to the true summit of Mangerton itself, before returning via the same route (or taking the steeper eastern arete of the Punchbowl).
