Mam Sodhail is mostly grassy without too much rock, however its sheer size, long ridges and fine corries together with its four tops named in the Munro Tables make it a first-rate mountain. The hill casts three ridges down towards Glen Affric, the most impressive of these being the east southeast ridge, which has two tops on it; Mullach Cadha Rainich (996 metres) stands at the midpoint of the ridge which runs for four kilometres to conclude at the other top of Sgurr na Lapaich (1036 metres), which is the most prominent part of the mountain when viewed from Glen Affric. It has the characteristics of a separate mountain and was regarded as a Munro in the original 1891 list, with Irvine Butterfield saying, The peak certainly does not lack character and many were disappointed to find that its original status was not restored in the seventh edition of Munros Tables. The other two ridges, which form a horseshoe around the Allt Coulavie valley to the south of the summit, carry the tops of An Tudair (1074 metres) and Creag Coire nan Each (1055 metres). The mountain's western flanks fall away towards Gleann a' Choilich, which drains northwards into Loch Mullardoch.
