The normal route of ascent for walkers is from the east. A path leaves the B8083 on the shores of Loch Slapin about 4 km after the village of Torrin. The path follows a burn, the Allt na Dunachie, into the corrie of Coire Uaigneich. From here a short steep route along the ridge leads to the summit. A small amount of scrambling is needed to reach the true top of the mountain.
Alternative routes follow the south ridge, or come from the north having traversed the Clach Glas ridge which links to the Red Cuillin peaks.
The view from the summit is dominated by the Black Cuillin.
