Coll

Small island of the Inner Hebrides, in Argyll and Bute unitary authority, Scotland, extending 19 km/12 mi in length, 16 km/10 mi west of mainland Ardnamurchan Point and 2 km/1 mi north of Tiree; population (2001) 164. Its terrain is low and rocky, with small bays and sandy machair (grassy coastal plains) on the western shores. The island was once renowned for its cattle and cheese, but production has fallen as crofting (a form of subsistence farming) has declined. Arinagour, on the east coast, is the principal village and harbour.
