🧭 Route Description
1. Glenbrittle to Coire Lagan
Begin at the Glenbrittle Campsite and follow the well-marked trail northeast along the Allt Coire Lagan burn. The path climbs gently through moorland and rocky terrain, offering views of Loch Brittle behind and the towering Black Cuillin ahead. After about 3.5 km, you’ll reach the stunning Lochan Coire Lagan, nestled beneath the cliffs of Sgùrr Alasdair and Sgùrr Sgumain.
2. The Great Stone Chute
From the lochan, head toward the base of the Great Stone Chute — a long, steep scree gully that climbs over 400 vertical meters. This section is the crux of the hike: loose, unstable scree makes progress slow and tiring. Poles can help, but expect to use your hands for balance. The chute narrows and steepens near the top, where care is essential.
3. Scramble to the Summit
At the top of the chute, you’ll reach a col between Sgùrr Alasdair and Sgùrr Sgumain. Turn left and follow the ridge northeast for a short but exposed scramble to the summit cairn. The rock is generally solid, but the drop-offs are significant — take your time and stay focused.
🌄 What to Expect at the Top
The summit of Sgùrr Alasdair offers breathtaking views across the Cuillin Ridge, Loch Coruisk, and the islands of Rùm and Soay. On clear days, you’ll see the full sweep of Skye’s rugged interior and the sea beyond. It’s a dramatic and humbling vantage point — one of the finest in Scotland Scotland Off the Beaten Track Live for the Outdoors Steven Fallon.
