Aonach Beag is the second Munro in a group of 4 forming a long craggy ridge from Strath Ossian in the SW to Loch Pattack in the NE. For convenience Aonach Beag is normally climbed with its nearest neighbours Beinn Eibhibb to the SW and Geal Charn to the NE saving far off Carn Dearg for another day.
Aonach Beag sits on the eastern rim of the deep Coire a' Charra Mhoir a deep gulley separating the hill from Beinn Eibhibb. Aonach Beag has a fine conical summit that is well seen from Glen Spean to the north.
Aonach Beag has 3 summit ridges running SW, NW and E. The SW ridge leads to a bealach at the head of Coire a' Charra Mhoir before pulling up the summit ridge of Beinn Eibhibb. The E ridge is wider and connects via another bealach to Geal Charn. The NW ridge drops down to the valley floor in An Lairig.
Aonach Beag and its neighbouring Munros are among the most remote in Scotland and are well placed back form any public roads. You can access them by a long walk in from either Glen Spean to the north or from Dalwhinne to the NE. You can also take the west highland train line to Corrour halt just west of Loch Ossian. This will reduce your walk in time.
