About Sgùrr Alasdair#

Sgùrr Alasdair is the highest peak on the Isle of Skye in northwest Scotland, rising to 992 metres (3,255 feet) and forming part of the island’s Black Cuillin ridge.

The mountain is characterised by steep, rocky ridges and is a popular objective for scramblers and mountaineers; the summit provides extensive views across Skye and, on clear days, out to surrounding islands and the mainland.

The Black Cuillin, including Sgùrr Alasdair, are formed from coarse-grained igneous rock that gives the peaks good grip for climbers but creates rugged, broken terrain.
