Buachaille Etive Beag forms a ridge about 3 km in length that runs in a southwest-northeast direction. It has two peaks of Munro status: Stob Dubh and Stob Coire Raineach. The latter became a Munro in the 1997 revision of Munro's Tables, in which all tops with a topographic prominence of more than 500 feet (152.4 m) were promoted to full Munro status.
