Stob a' Choire Mheadhoin has a long NE ridge which descends for over five km to the hamlet of Fersit at the head of Loch Treig. This ridge is the most common route of ascent and though mostly a moderate gradient it does have several steep sections, most notably the rocky climb up to Meall Cian Dearg which requires some mild
scrambling. The mountains eastern flank falls steeply to Loch Treig with the slope rising from loch side to summit for 850 metres and an average gradient of over 30 degrees. These slopes are well seen when travelling on the
West Highland Railway on the east side of the loch. A ridge goes SW from the summit to connect to the mountains twin Munro of Stob Coire Easain, this ridge hugs the lip of the impressive Coire Easain Beag which stands between the two mountains. This corrie has patches of red rock on its upper slopes especially on its Stob a' Choire Mheadhoin side, a point on the ridge at the head of the corrie is actually named Càrn Dearg (Red Cairn) on the
OS map. There are several corries on the eastern side of the mountain, the most impressive of these by far is Coire Meadhon which falls directly from the summit with steep crags on its southern side. The northern slopes of the mountain descend into Coire Laire which is drained by the Allt Laire which goes north to join the River Spean as does all rainfall from the mountain. ==Ascents==
