Islands of the Clyde

The Islands of the Firth of Clyde are the fifth largest of the major Scottish island groups after the Inner and Outer Hebrides, Orkney and Shetland. They are situated in the Firth of Clyde between Ayrshire and Argyll and Bute. There are about forty islands and skerries, of which only four are inhabited and only nine larger than 40 hectares (99 acres). The largest and most populous are Arran and Bute, and Great Cumbrae and Holy Isle are also served by dedicated ferry routes. Unlike the four larger Scottish archipelagos, none of the isles in this group are connected to one another or to the mainland by bridges.

The geology and geomorphology of the area is complex and the islands and the surrounding sea lochs each have distinctive features. The influence of the Atlantic Ocean and the North Atlantic Drift create a mild, damp oceanic climate.

The larger islands have been continuously inhabited since Neolithic times, were influenced by the emergence of the kingdom of Dál Riata from 500 AD and then absorbed into the emerging Kingdom of Alba under Kenneth MacAlpin. They experienced Norse incursions during the early Middle Ages and then became part of the Kingdom of Scotland in the 13th century. There is a diversity of wildlife, including three species of rare endemic tree.
