Beinn Challuim

Beinn Challuim stands in the Breadalbane region of the Scottish Highlands, east of Tyndrum village. It is a Munro rising 1,025 metres above sea level in the ancient Forest of Mamlorn. The mountain overlooks the northern edge of Loch Lomond and the Trossachs National Park. Its broad grassy slopes are seen from the A82 in Strath Fillan. From the north it shows a steep rocky face above Glen Lochay. The name means ‘Callum’s mountain’, linking it to Saint Columba. The mountain qualifies as both a Munro and a Marilyn with a prominence of 450 metres. Its summit ridge connects two corries, Coire nan Each to the west and Coire Challuim to the east. Water from the slopes reaches both the Firth of Tay and the Firth of Clyde. A subsidiary summit, the South Top at 998 metres, lies 600 metres south of the main peak. The two are joined by a narrow ridge that can be confusing in poor visibility. Walkers usually start at Kirkton Farm in Strath Fillan to visit the ruins of St Fillan’s Priory before climbing grassy slopes to the summit ridge. Another route follows Glen Lochay for nine kilometres to reach the eastern ridge. Hamish Brown suggests a quieter northern approach from Auch, involving mild scrambling up the north-west ridge. The summit, named Stob Glas, carries a large cairn above sheer northern cliffs. From the top there are fine views of peaks around Tyndrum and Crianlarich.
