Beinn Liath Mhor is a fine Munro separating Strath Carron in the south and Glen Torridon to the north. With its neighbouring peaks of Sgorr Ruadh and Fuar Tholl (not a Munro) they make a fine set of mountains and are connected by a series of ridges and cols.
Beinn Liath Mhor has a 2km long summit ridge stretching E- W. There are several tops on the ridge with the western one being the highest thus the true Munro summit. There are steep crags on both sides of the summit with a lot of quartzite scree.
A circular route is easily achieved starting from the east traversing the ridge and descending west after the summit. This is a superb outing with scrambling opportunities in abundance. The route can be extended by continuing on the ridge after Beinn Liath Mhor. The ridge curves round the head of Coire Lair and on to the summit ridge of neighbouring Munro Sgorr Ruadh. Achnashellach to the SE makes a logical starting point and there is parking available.
