The south side of the glen is marked by a succession of distinct peaks: Buachaille Etive Beag at the eastern end, followed by the Three Sisters, shoulders of the Bidean nam Bian massif which are subdivided by Coire Gabhail and Coire nan Lochan. The name Coire Gabhail (corrie of the bounty, or hollow of capture) refers to former times when the corrie was used by members of Clan Macdonald to hide cattle and other livestock, whether their own or stolen from others. The wide flat glen is well suited for this purpose since from Glen Coe it appears to be a normal v-shaped glen approached only by a steep narrow gorge. Summits in the Bidean nam Bian massif include Stob Coire Sgreamhach, Stob Coire nan Lochan and Aonach Dubh (the third sister). By contrast the north side of the glen is a stark wall of mountain, the Aonach Eagach ridge. The ridge is crossed at the eastern end by the Devil's Staircase, an old military road opposite Buachaille Etive Mòr. The western end terminates with the conical Pap of Glencoe (Sgùrr na Cìche), above Glencoe village, at the point where the glen opens out to Loch Leven.
