Fionn Choire, Bealach nan Lice, Bruach na Frithe

This is a serious Black Cuillin mountain day rather than a simple hillwalk: about 14 km / 8.7 miles with roughly 900 m / 2,950 ft of ascent, starting near Sligachan Hotel, Sligachan, Isle of Skye IV47 8SW, beside the old road and the Skye Mountain Rescue base. The usual line heads up Glen Sligachan-side approaches into Fionn Choire, climbs to Bealach nan Lice, then traverses beneath Sgùrr a’ Fhionn Choire to gain the ridge of Bruach na Frìthe. This is generally classed as difficult because the terrain is steep, loose in places, often wet, and very exposed to wind and cloud once you reach the upper corrie and ridge.

The opening section is comparatively straightforward. From the roadside start near Sligachan, a clear path leads south-west on rough but well-used ground, with the dark skyline of the Black Cuillin building ahead. Early progress is usually fast, but the route should not be underestimated: even the lower approach can be boggy after rain, and the mountain character becomes obvious as the path steepens toward the corrie. Expect around 4 to 5 km / 2.5 to 3.1 miles of approach walking before the route really bites into the climb. HiiKER is especially useful here if visibility is poor, because several trods and stony lines can tempt people off the cleanest ascent line. (thegreatoutdoorsmag.com)

Through Fionn Choire

Fionn Choire is the heart of the route and the point where the day changes from a mountain walk into a full Cuillin outing. The path climbs into a dramatic corrie enclosed by steep rock architecture, with the line to Bealach nan Lice rising at the head of the basin. The ascent here is sustained, and the footing can alternate between pitched path, scree, boulders, and worn gravel. In wet weather, the burn crossings and polished rock can become slippery; in mist, the corrie can feel confusingly enclosed, with cliffs and ribs obscuring the onward line. (thegreatoutdoorsmag.com)

Bealach nan Lice is one of the major landmarks of the day, sitting high on the Cuillin between Am Basteir and Sgùrr a’ Fhionn Choire. Reaching it usually means you have gained most of the day’s height, roughly 800 m / 2,625 ft or so from the start, but not the full effort. The bealach is a spectacular mountain pass rather than a comfortable rest stop: it can funnel wind, hold lingering snow patches outside high summer, and feel abruptly alpine compared with the lower approach. From here, the views open dramatically across the main ridge and into the rough interior of the Cuillin. (komoot.com)

Traverse to the summit

From the bealach, the usual route does not simply go straight up. Instead, it traverses beneath the north side of Sgùrr a’ Fhionn Choire before gaining the east ridge of Bruach na Frìthe. This section deserves respect. Although it is often described as a walking route to a Munro in the Cuillin, it still crosses steep mountain terrain where a slip could have serious consequences, especially if the path is greasy, snow-covered, or hidden by mist. The final ridge is easier than many neighbouring Cuillin peaks, but it is still rocky and can require hands for balance depending on conditions and confidence. (thegreatoutdoorsmag.com)

The summit of Bruach na Frìthe stands at about 958 m / 3,143 ft and is notable for being the only Black Cuillin summit with an Ordnance Survey trig pillar. On a clear day, the panorama is one of the finest on Skye: the jagged spine of the main Cuillin dominates the south and east, while the sea lochs, Red Cuillin, and wider island landscape spread out beyond. In cloud, though, the summit can feel featureless and disorienting, so bearings and careful route-finding matter just as much on the descent as on the climb.
