Brodick (Scottish Gaelic: Breadhaig or Tràigh a' Chaisteil ("Castle Beach")) is the main settlement on the Isle of Arran, in the Firth of Clyde, Scotland. It is halfway along the east coast of the island, in Brodick Bay below Goat Fell, the tallest mountain on Arran. The name is derived from Norse roots meaning "Broad Bay".The harbour receives the main ferry between Arran and the mainland via Ardrossan. Brodick Castle is a former residence of the Dukes of Hamilton.
