Rising a kilometer out of the storm-scoured waters around Scotland's Isle of Skye is a dark battlement of pinnacles and ridgelines: the Cuillin. While 19th-century climbers flocked to the Alps, the toughest mountaineering expedition in the British Isles lay untrodden. Here Simon Ingram takes a journey through the history and into the heights of the Cuillin of Skye, from the ridge's violent birth to the tales of its pioneers, its thrills, and its legends.
