SGURR A' GHREADAIDH

'Sgurr a' Ghreadaidh' is the highest summit on the northern half of the Black Cuillin ridge. Like the rest of the range it is composed of gabbro, a rock with excellent grip for mountaineering.
This is one of the trickier main Black Cuillin peaks to ascend. The simplest route ascends via the col of An Dorus (the Door), most easily reached from Glen Brittle. The mountain has two summits, separated by a knife-edged arete which is probably the finest in the British Isles. At the time of the first ascent, John Mackenzie was aged just 14. He had earlier repeated the ascent of Sgurr nan Gillean aged 10. Mackenzie became the first British mountain guide and perhaps the most prolific of the pioneers of mountaineering in the Cuillin.
