Chno Dearg expansive northern flank falls gradually to Glen Spean and the shores of Loch Laggan, the lower part being covered with an extensive forestry plantation. These northern slopes can be boggy at times with numerous small streams, and contain the subsidiary top of Meall Chaorach (815 metres) which is situated 1.5 km from the main summit. On the western side of the hill is Coire an Lochain, a shallow hollow with gentle slopes which contains Lochan Coire an Lochain.
