Standing in a region which has some of the highest mountains in the UK, Beinn Bhàn can be easily overlooked, however it is conspicuous in the view from the Commando Memorial at Spean Bridge, where its long NW ridge is well seen rising from Glen Mallie to the summit ridge overlooking the Great Glen. The hill has three notable corries on its slopes, the south facing Coire Mhuilinn (corrie of the mill) above Glen Loy is smooth and grassy, while the two north facing corries of Coire Bhotrais (corrie of the rough miry holes) and Coire Dubh (black corrie) are more rocky and steeper in nature. All three corries bite significantly and high into the hill to give a two kilometre long narrow curving summit ridge which is above the 750 metre contour for its entire length. The highest point stands at the eastern end of the ridge and there are two lesser and unnamed tops, both with a height of 771 metres situated at the midpoint and western end. 200 metres west of the main summit are several springs which emerge on the summit ridge and are the origins of the stream which flows down Coire Mhuilinn.
