Loch Fyne extends north from the Sound of Bute and, at 65 kms, is the
longest »sea loch« on the west coast of Scotland. It is noted for its
oyster and herring fisheries, with Loch Fyne kippers widely considered
the best available. During World War II Loch Fyne served as a training
ground for the Normandy landings. Later on it was used by the Royal
Navy to test torpedoes. Beside the herrings and oysters, Loch Fyne is
home to wild life such as otters, dolphins, seals, and (in summer)
basking sharks.

The name »Loch Fyne« derives from the Gaelic for »Loch of the Wine (or
Vine)«, even though there is no evidence of grapes growing in the area.
