Gigha Oysters are grown in the clear tidal water off the little Isle of Gigha, just off the Kintyre coast. This is a producer rather than a visitor attraction, so the oysters mostly reach you through restaurants and island outlets rather than at a farm gate. Gigha is a short 20-minute CalMac hop from Tayinloan on Kintyre, and the same island is home to the Wee Isle Dairy café.
