A Ghlas-bheinn is the most westerly Munro in this region and one of the more accessible Munros due to its close proximity to the A87 at Loch Duich. From here the Munro is well seen. A Ghlas-bheinn has a "knobbly" summit with lots of crags and steeps drops on all sides, for such a small Munro it packs quite a punch. The summit sits at the trisection of 3 ridges. The southern ridge leads to a high col before climbing the north west ridge of its much larger neighbour Beinn Fhada. The two are normally climbed together. The northern ridge leads to subsidiary peaks Creag na Saobhie and Meall Dubh. Finally the western ridge leads down to Dorusduam and easy tracks out to the A87. All ridges are steep and craggy and offer a few scrambling opportunities if you look for them.
From the summit of A Ghlas-bheinn you get fantastic views of Beinn Fhada and its impressive array of corries. As mentioned A Ghlas-bheinn is normally combined with Beinn Fhada further south to make a great day on the hills. Morvich just off the A87 makes a logical starting point with a circular route over the two Munros possible.
