Bla Bheinn North and South Top from Arincreaga

This is a short but very serious mountain day on the Isle of Skye, climbing Blà Bheinn from the north end of Loch Slapin near the roadside parking by the Allt na Dunaiche bridge on the B8083, between Torrin and Kilmarie. The usual start is close to grid reference NG 560 216, which corresponds to the small parking area at the head of Loch Slapin rather than a formal village trailhead. (walkhighlands.co.uk)

Although the outing is only about 9 km / 5.6 miles, the figures are deceptive. With roughly 900 metres / 2,950 feet of ascent packed into a relatively compact route, and with steep, rocky ground high on the mountain, this is best treated as an extra-difficult hike suited to strong hillwalkers who are comfortable on rough terrain and in rapidly changing mountain weather. Blà Bheinn stands apart from the main Black Cuillin ridge, but it is still very much a Skye mountain: rugged, exposed, and demanding respect. The summit itself rises to 929 metres / 3,048 feet.

The route begins on a good path heading away from the road and crossing near the burn, then works gradually into Coire Uaigneich, the great corrie beneath the mountain. The first section is often the easiest going of the day, giving you time to settle into the climb while the bulk of Blà Bheinn grows steadily ahead. Early on, expect wet ground after rain, stony pathwork, and a sense of committing to a much bigger mountain than the mileage suggests. Walkhighlands notes the route starts from the car park off the B8083 near Loch Slapin, and the established line of ascent heads into the corrie before climbing the mountain from the east.

The climb into Coire Uaigneich

After roughly 1.5 to 2 km / 0.9 to 1.2 miles, the route steepens more decisively as it enters the corrie. This is where the day starts to feel strenuous. The path becomes rougher and more eroded in places, and the ascent turns into a sustained grind over rock, gravel, and steep mountain turf. A common mistake here is to drift onto looser or less efficient lines, especially in mist, so careful navigation matters. If carrying navigation tools, plan the route in HiiKER before setting out and do not rely on visibility alone. The corrie is enclosed and dramatic, but once cloud drops, features can become confusingly similar. The need to follow the correct line up the rib rather than wandering across awkward ground is also noted in route descriptions for the mountain. (getlostmountaineering.co.uk)

As height is gained, views open over Loch Slapin, with the sea loch and surrounding crofting landscape giving a striking contrast to the dark, broken mountain architecture above. The mountain’s eastern side is the standard walkers’ approach because it avoids the technical climbing terrain found on ridges such as Clach Glas, which is a mountaineering objective rather than a hiking extension. Even so, the upper mountain still involves hands-on movement in places and should not be underestimated. (walkhighlands.co.uk)

Upper slopes, North Top and South Top

Higher up, the route becomes increasingly rocky and exposed. The final climb to the main summit involves steep, bouldery ground and short sections where balance, foot placement, and confidence are important. In dry, calm weather this is an exhilarating finish; in rain, strong wind, or low cloud it can feel much more serious. The cliffs immediately north of the main top are a particular hazard, and descent lines need care. Walkhighlands specifically warns of steep cliffs just north of the summit area, which is one reason accurate route-finding is so important on the return. (walkhighlands.co.uk)

If your version of the route includes both the North Top and South Top, expect extra effort beyond the main summit. The traverse adds more uneven, rocky ground and can feel slower than it looks on the map. Distances are short, but progress is often measured by terrain rather than mileage. Allow time for backtracking or for a careful out-and-back to the subsidiary top if conditions are not ideal. On a mountain like this, wind, wet rock, and fatigue can turn a simple-looking extension into the crux of the day.
