Mull's highest peak, and the only island Munro outside Skye, Ben More (966m) offers spectacular views of surrounding islands. A trail leads up from Loch na Keal, by the bridge on the B8035 8 miles southwest of Salen. Return the same way or continue down the narrow ridge to the eastern top, A'Chioch, then descend to the road via Gleann na Beinn Fhada.
See Ordnance Survey (OS) 1:50,000 map sheet 49. The glen can be wet and there's not much of a path. The return trip is 6.5 miles; allow five hours.
