The upper slopes of An Gearanach are basically a north-south summit ridge just over a kilometre in length with steep flanks which drop into the valleys of the Allt Coire a' Mhail to the west and the Allt Coire na Gabhalach to the east. At the northern end of the mountain are three ridges which go roughly NW, north and NE descending to upper Glen Nevis. To the south is a ridge which descends to the Bealach a' Chadah (857 metres) before continuing to the adjoining Munro of Stob Coire a' Chàirn. An Gearanach is a popular mountain, not just because of its Munro status but because it is part of one of the best and most exposed ridge walks in the whole of Scotland, the Ring of Steall. This route takes in the three other Munros of Stob Coire a' Chàirn, Am Bodach and Sgurr a' Mhàim during a circuit of the Allt Coire a' Mhàil, a glen which feeds the An Steall Ban waterfall. The An Steall Bàn (the white spout) is a fine sight as it drops 120 metres down the northern lower slopes of An Gearanach. The base of the falls is passed on the approach to the mountain from Glen Nevis.
