The rocky, wild and virtually treeless island of Coll was first settled in the Stone Age. Dotted with ruined cottages, this bird haven is picturesquely clad in flower-dotted machair, fringed by silver-white beaches, and offers refreshing bike rides and walks. Lying four miles west of Mull, Coll measures 13 miles in length and four miles across at its widest point. Arinagour is the main village which is home to half of the island’s population.
