Stac Pollaidh is one of the most distinctive mountains in Scotland — a narrow, knobbly quartzite ridge rising sharply from the flat bogland of Coigach, visible from the road to Achiltibuie and instantly recognisable in profile. At 613 metres it is not particularly high, but the ascent feels much more serious than the numbers suggest, with a scramble along the exposed ridge to the highest point.
The route starts from a car park on the single-track road between Ullapool and Achiltibuie. A well-worn path circles the mountain before attacking the ridge directly; most walkers take two to three hours. The views from the top are among the best in the area, stretching west to the Summer Isles and Tanera Mòr, north to Suilven and Canisp, and south across Loch Lurgainn. The summit ridge requires hands-and-feet scrambling in places and should not be attempted in poor visibility.
