Cul Beag
Cul Beag is the smaller, steeper neighbour of Cul Mor in the Coigach hills, sitting south of Stac Pollaidh on the road from Drumrunie to Lochinver. The mountain is built of Torridonian sandstone and rises straight from Loch Lurgainn in a single dramatic line — short on metres, big on character. From the summit you look straight across to Stac Pollaidh's pinnacles and out over Suilven, Quinag and the rest of Assynt. Short by Corbett standards but steep enough to feel like a proper hill day.
Gaelic: “small” · Pronunciation: cul bek

Standard route
moorland path 20% · rough heather 30% · sandstone ridge 35% · summit area 15%
The standard route starts from a layby on the Drumrunie–Achiltibuie road (A835/the single-track road west) below the Linneraineach plantation. A vague path heads south-east across moorland and climbs steeply onto the broad south ridge. From the south top the ridge narrows briefly before opening onto the summit plateau. Return by the same line, or descend north-west into Coir' an Lochain Sgeireach for a circuit (rough). Allow 4–5 hours.
Terrain
Short, sharp and rough underfoot. The lower moorland is wet and trackless; the steep central section is on grass with rocky steps; the summit ridge is sandstone slab. In any wet weather the slabs are slippery — care needed on descent.
In winter
Cul Beag's steep upper slopes hold snow longer than the elevation suggests because of the aspect, and the summit slabs ice up readily. The descent line is committing in poor visibility. A small but serious winter hill — full kit required if snow lies.
This hill is in the Torridon SAIS forecast area. Check SAIS forecasts in winter (December–April).
