Standard route
heather moorland 60% · rocky slopes 25% · grass slopes 15%
From the National Trust car park at Glenfinnan, take the path through the woods toward the viaduct, then cross the railway and climb steeply up the south-east ridge. A clean ascent on heather and grass to a small cairn with a memorable view down to the loch and the Jacobite monument. About 5 hours circular.
Terrain
A clean ridge of heather and short turf with occasional rocky steps. The lower wooded section is wet after rain and has slippery roots; the open ridge is among the better walking in this area.
In winter
At 812m and west-facing, the hill catches the brunt of winter Atlantic systems. The south-east ridge is the safer line in snow; the north-west drops are heavily corniced in good winters. Crampons useful from January to March on the upper third.
This hill is in the Glen Coe SAIS forecast area. Check SAIS forecasts in winter (December–April).
