Fiona, lies about to the southwest. An alternative northern route heads up from Corrie Hallie, which lies about south of Dundonnell. This route, some in length, climbs steeply up the headwall of the corrie of Glas Tholl to reach the main ridge just north of Bidein a' Ghlas Thuill. Both of the above routes, however, miss out the central section, for which An Teallach is best known. A route reaching the summits from the south starts from near Corrie Hallie. It then follows a track (later a path) southwest for about . Then it breaks off to the north, climbing the southern end of the ridge via a subsidiary summit known as Sàil Liath. Heading northwest towards the Corrag Bhuidhe buttresses a choice must be made. One may either scramble over them directly (including the crossing of Lord Berkley's Seat), or take the bypass path on the southwest side. This path is eroded in some places and should not be regarded as an easy option. The winter traverse of the ridge is probably more demanding than that of Liathach or the Aonach Eagach.
