Great Cumbrae (Scottish Gaelic, Cumaradh Mòr; also known as Cumbrae or the Isle of Cumbrae) is the larger of the two islands known as The Cumbraes in the lower Firth of Clyde in western Scotland. Home to the National Watersports Centre, the Cathedral of the Isles and the University Marine Biological Station, Millport, the holiday island has an 18-hole golf course which sweeps almost to the summit, and a round-island road much favoured for family cycle runs.
