About Isle of Coll

Coll is a low-lying, sandy island in the Inner Hebrides, west of Mull and north-west of Tiree. Unlike its mountainous neighbours, it is mostly machair, dunes and freshwater lochs, and it remains one of the quietest of the inhabited Hebridean islands with a population of around 200.

The story of Isle of Coll

Breachacha Castle, a 15th-century tower house on the south coast, was the seat of the MacLeans of Coll and withstood sieges by the MacLeans of Duart before passing to the Campbells in the late 19th century. Coll suffered heavily in the Clearances: in 1851 the laird removed nearly half the population to make way for sheep, and the island's numbers fell from over 1,000 to a few hundred within a generation. The island is the setting for Mairi Hedderwick's Katie Morag children's books, whose fictional island of Struay draws directly on Coll's crofts, ferry and schoolhouse. Prehistoric standing stones and a Bronze Age cairn near Arinagour point to settlement stretching back thousands of years.

Visiting with care

Take the CalMac ferry from Oban to Arinagour, often combined with a Tiree sailing, and explore the island on foot or by bicycle. The dunes at Crossapol, the machair lochs and the white-shell beaches of the west coast are the chief draws, and corncrakes can be heard in the summer meadows.
