NG4862219573 From the landing stage take the well-used path east. Soon join the Scavaig River, reputedly the shortest named river in the country, which is followed upstream to the outflow of Loch Coruisk. Hop the stepping stones here (care if the water is high) and follow the eroded path above the east shore of Loch Coruisk. the surroundings are as ruggedly grand as they come. The path soon braids into several trails; stay right, on a rising traverse away from the loch. Pass beneath a big slabby crag to reach a path junction near the Allt Choire Riabhaich.

NG4932720502 Turn right to follow the rough path uphill, just south of the cascading burn. It is possible to make a beeline for Sgurr na Stri almost straight away, but it's a steep and pathless climb; better to continue NE on the main path for a few hundred metres. A burn that drains the northern flank or Sgurr na Stri is a good marker.

NG4962920766 Turning hard right, follow this burn uphill, roughly SSE. There's not much of a path, but the general gist is obvious. Beyond the burn, follow your nose south, climbing steadily on rough and complex ground. As height is gained a clearer path takes shape, following the broad rocky ridge - with some scope for easy scrambling - to reach a vague fore-summit immediately overlooking Loch Scavaig. This is arguably the best viewpoint on the Cuillin. The high point is a little way south over a jumble of rocky hummocks. It's also worth visiting the slightly lower east top while you're here.

NG4995519276 Return the way you came... or improvise a slightly different variation... it's that sort of ground.
