Beinn a' Chaorainn is basically a north-south orientated ridge which looks quite an undistinguished bulk when viewed from Roughburn (see picture), the best view of the mountain being from the east where the crags of Coire na h-Uamha give the mountain some character. This corrie's name translates as the Corrie of the Cave although no significant cave is known in its environs although there are several small lochans within its higher recesses. It is drained by the Allt na h-Uamha whose glen separates the mountain from Creag Meagaidh massif to the east. Part of these eastern flanks of the mountain are clothed in coniferous woodland below the 550 metre contour. Coire na h-Uamha is split into two distinctive parts by an eastern ridge which gives a feasible route of ascent from the foot of the coire directly to the main summit, however some care is needed and in Winter conditions it is ranked as a Grade I route.
