Loch Fyne; meaning Loch of the Vine or Wine, is a sea loch off the Firth of Clyde and forms part of the coast of the Cowal peninsula. Located on the west coast of Argyll and Bute, Scotland. It extends 65 kilometres (40 mi) inland from the Sound of Bute, making it the longest of the sea lochs. It is connected to the Sound of Jura by the Crinan Canal. Although there is no evidence that grapes have grown there, the title is probably honorific, indicating that the river, "Abhainn Fìne", was a well-respected river.
In the north the terrain is mountainous, with the Arrochar Alps, Beinn Bhuidhe, Glen Shira, Glen Fyne, Glen Croe, Arrochar, Tyndrum and Loch Lomond nearby.
It is overlooked by the Tinkers' Heart, an old travelers' monument[1]
Loch Fyne is a popular area for sport diving and fishing. It is also a popular tourist destination with attractions such as Inveraray Castle and the nearby ruins of Castle MacEwen and Old Castle Lachlan.
The village of Portavadie is on the east shore of the loch. A passenger ferry traverses the loch to Tarbert from the slipway at Portavadie.
Dolphins, seals and otters inhabit the loch, and basking sharks can appear in its waters during the summer months. A Ross's gull was present at the loch in early 2007.
