Munro · Glen Coe & Lochaber
Glas Bheinn Mhor
Glas Bheinn Mhor (997m) is a Munro set in the country between Glen Etive to Glen Lochy. It shares ridgeline connections with neighbouring hills, making it a natural addition to a longer day combining two or three summits. The summit, marked by a cairn, gives views of sea lochs, dramatic ridges and the peaks of the western Highlands. The nearest town is Fort William in Argyll and Bute/Highland.

Standard route · 17km
Standard route
The standard route is a longer walk with a gradual approach covering approximately 17km with 878m of total ascent — a full day on the hill. Lower slopes cross steep-sided glens with birch and oak woodland. Higher up, the terrain changes to volcanic and metamorphic rock, steep ridges and buttresses. Good stalkers' paths on popular routes but remote sections, particularly around Knoydart, are rough and pathless. The summit is marked by a cairn.
Terrain
Above 700m the ground is fully exposed to weather from all directions. Good stalkers' paths on popular routes but remote sections, particularly around Knoydart, are rough and pathless. The connecting ridges to adjacent hills are well-defined but involve noticeable re-ascent.
In winter
In winter, Glas Bheinn Mhor is a serious proposition. Heavy snowfall and rapid freeze-thaw cycles make conditions changeable. Avalanche risk on steeper slopes is real — check the SAIS forecast before heading out. Short winter days mean an early start is essential, particularly on longer routes.
