Like its more northerly neighbor, it is an area of astonishing but stark beauty, with mountains rising sheer to dizzying heights from quiet lochs. The highest summit is Ben More Coigach, 743 metres.

Achiltibuie and its smaller adjoining hamlets form the parish of Coigach, a traditional crofting and fishing community of a couple of hundred houses sprinkled between mountain and shore on a peninsula looking over the Summer Isles and the sea.
