Sgùrr Alasdair (pronounced [s̪kurˠˈal̪ˠəs̪t̪ɪɾʲ]) is the highest peak of the Black Cuillin, and the highest peak on the Isle of Skye and in the Inner Hebrides, and indeed in all the Scottish islands, at 992 m (3,255 ft). Like the rest of the range it is composed of gabbro, a rock with excellent grip for mountaineering. It is named after Alexander Nicolson, who made the first recorded ascent in 1873.^[2] Prior to this the mountain had been locally known as Sgurr Biorach.^[3]

As with other hills of the Cuillin, a head for heights and scrambling ability are needed to attain the summit. The least technical route follows a feature known as the "Great Stone Chute", a scree gully that leads up from the corrie of Coire Lagan to a bealach just below the main ridge. From this col, a pleasant scramble (Grade 2 standard) up the well scratched east ridge leads to the narrow summit.^[4]

Other routes require scrambling ability or rock climbing; while there are rock climbs directly up the flanks, the only other way of reaching the summit via a ridge is the south-west ridge, a Grade 3 scramble that begins up a scratched chimney which can be accessed from the summit of Sgùrr Sgumain or from Coir' a' Ghrunnda; there is also a slightly easier route from the top of this chimney directly up a shallow gully on the south face. The summit of Sgùrr Alasdair can be attained by a short detour (from Sgùrr Theàrlaich) off the main ridge by climbers undertaking the full traverse of the Cuillin ridge, or by those following the circuit of Coire Lagan.
