Aonach Beag
Aonach Beag (1234m) is a Munro set in the country between Fort William to Loch Treig & Loch Leven. With 404m of prominence it stands well apart from its neighbours, a genuinely isolated summit that demands a dedicated day. The summit, marked by a small cairn, gives views of sea lochs, dramatic ridges and the peaks of the western Highlands. The nearest town is Fort William in Highland.

Standard route · 20km
Standard route
The standard route is a longer walk with a gradual approach covering approximately 20km with 1086m of total ascent — a long and demanding day. 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 small 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 hill's high prominence means the approach involves significant re-ascent — there are no easy shortcuts from neighbouring peaks.
In winter
In winter, Aonach Beag 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.
