Baosbheinn which is made up of Torridon Sandstone reaches a height of making it the 56th highest Corbett and the 277th highest Marilyn. It is a long elongated mountain with a NW-SE orientation, its summit ridge is impressive, barely dropping below the contour in its length. Its SW slopes drops away steeply and rockily towards Loch a' Ghobhainn while its NE slopes are less precipitous, throwing out a series of spurs which produces three craggy corries. Strong hill walkers can climb Baosbheinn with the adjacent Corbett of Beinn an Eoin which stands across Loch na h-Oidhche and gives a demanding circular walk of which takes between six and nine hours.
