Caledonian MacBrayne sets the rhythm at Castlebay, the small harbour that anchors the Isle of Barra to the rest of Scotland. Its services run from here to Oban on the mainland and to Lochboisdale on South Uist, making this first and foremost a lifeline ferry port rather than a commercial cargo gateway. Freight moves almost entirely across the RoRo linkspan: groceries, building materials and island supplies arrive as accompanied vehicles or trailers, and there is no container terminal or conventional break-bulk handling. The single berth offers roughly 65 m of quay at about 5.2 m depth, supported by fresh water, gas-oil bunkers and a mobile crane, while the bay also shelters local fishing vessels. Shippers with containerised or international loads should route via Oban for the mainland, with Stornoway handling larger volumes for the Outer Hebrides.
