Ben Cruachan is a mountain that rises to 1126 m, the highest in Argyll and Bute, Scotland. It gives its name to the Cruachan Dam, a pumped-storage hydroelectric power station located in a cavern inside the mountain. It is the high point of a ring of mountains, known as the Cruachan Horseshoe, that surrounds the power station reservoir. The horseshoe includes a further Munro (Stob Diamh), a Corbett (Beinn a' Bhuiridh), and several subsidiary summits. "Cruachan!" is the battle cry of Highland clans Campbell and MacIntyre.
