Munro · North-West Highlands
Beinn Liath Mhor
Beinn Liath Mhor (926m) is grey, a prominent mountain in the wild sandstone mountains of the North-West Highlands. Its 271m of re-ascent gives it a distinct identity — this is no subsidiary top but a hill worth visiting in its own right. The summit, marked by a large cairn, gives views of the Minch, the Outer Hebrides and the rugged Atlantic coastline. The nearest town is Ullapool in Highland.
Gaelic: “mountain, peak, grey, big” · Pronunciation: bine lee-ah vore

Standard route · 16km
Standard route
The standard route is a longer walk with a gradual approach covering approximately 16km with 815m of total ascent — a full day on the hill. Lower slopes cross heather moorland and rough grass, often boggy and pathless. Higher up, the terrain changes to exposed Torridonian sandstone or quartzite, increasingly rocky. Paths are often absent above the glen floor — expect rough, trackless terrain requiring confident navigation. The summit is marked by a large cairn.
Terrain
Above 700m the ground is fully exposed to weather from all directions. Paths are often absent above the glen floor — expect rough, trackless terrain requiring confident navigation. The connecting ridges to adjacent hills are well-defined but involve noticeable re-ascent.
In winter
In winter, Beinn Liath Mhor is a serious proposition. Full winter conditions are common from November to April with snow, ice and fierce Atlantic winds. An ice axe and crampons are essential above 600m. At this latitude, daylight hours drop below seven in December — start early and carry a headtorch.
