Bidean Nam Bian

Bidean nam Bian, lying to the south of Glen Coe, Highland, Scotland, is the highest point in the former county of Argyll. It is a complex mountain, with many ridges and subsidiary peaks, one of which, Stob Coire Sgreamhach, is classified as a separate Munro.

The most noticeable features of Bidean nam Bian are the famous Three Sisters of Glen Coe, three steeply-sided ridges that extend north into the Glen. Two of the sisters, Gearr Aonach (Short Ridge) and Aonach Dubh (Black Ridge) converge at Stob Coire nan Lochan, a 1,115 m (3,658 feet) subsidiary peak of Bidean nam Bian that lies about 1 km to the northeast of the actual summit. The final, most easterly sister, Beinn Fhada (Long Hill), joins the Bidean nam Bian massif at the summit of Stob Coire Sgreamhach.

Beinn Fhada is separated from Gearr Aonach by a glen known as Coire Gabhail. This translates to Glen of Capture, however the glen is more normally known as the Hidden or Lost Valley. Either name may be considered appropriate since it is believed that in former times the valley was used by members of Clan Macdonald to hide stolen Clan Campbell cattle. The glen is ideal for this purpose since it is blocked by a glacial landslip, and from Glen Coe appears as a narrow gorge. In fact, once past the landslip the floor of the glen is wide and flat – ideal for cattle. The path from Glen Coe through the gorge into Coire Gabhail is a popular short walk (around 4 km in total), though it is rough in places.
