Bidean Nam Bian (Munro)

The most notable features of Bidean Nam Bian are the famous Three Sisters of Glen Coe, three steep ridges that run northwards into the Glen. Two of the sisters, Gearr Aonach ( Short Ridge ) and Aonach Dubh ( Black Ridge ), converge at Stob Coire nan Lochan, a subsidiary 1,115m (3,658ft) peak of Bidean Nam Bian, which lies about 1km (0.5 miles) north-east of the present summit. The final, easternmost sister, Beinn Fhada ( Long Hill ), joins the Bidean Nam Bian massif at the meeting of Stob Coire Sgreamhach.

Beinn Fhada is separated from Gearr Aonach by a valley known as Coire Gabhail. This can be translated as the Glen of Capture, but the Valley is more normally known as the Hidden or Lost Valley, as it has a large flat area hidden from Glen Coe by the landslide that blocked the entrance and allowed a loch to form.  The Valley was used by the Macdonald clan to hide their cattle from raiders or to hide cattle they had stolen themselves. The steep and rugged path up from Glen Coe runs along a wooded gully and is a popular short walk (about 4 kilometers, although it involves a river crossing and some rocky sections.
