Kyles of Bute in the context of National scenic area (Scotland)

The Firth of Clyde is the estuary of the River Clyde, on the west coast of Scotland. The Firth has some of the deepest coastal waters of the British Isles and is sheltered from the Atlantic Ocean by the Kintyre Peninsula. The Firth lies between West Dunbartonshire in the north, Argyll and Bute in the west, and Inverclyde, North Ayrshire and South Ayrshire in the east. Kilbrannan Sound is a large arm of the Firth, separating the Kintyre Peninsula from the Isle of Arran. The Kyles of Bute separates the Isle of Bute from the Cowal Peninsula. The Sound of Bute separates the islands of Bute and Arran.

The Highland Boundary Fault crosses the Firth. The Firth also played a vital military role during World War II.

Cowal (Scottish Gaelic: Comhghall) is a rugged peninsula in Argyll and Bute, on the west coast of Scotland. It is connected to the mainland to the north, and is bounded by Loch Fyne to the west, by Loch Long and the Firth of Clyde to the east, and by the Kyles of Bute to the south.

Argyll is the historic county that the Cowal peninsula was within. Inveraray was the county town.

The Sound of Bute is a broad sound, separating the islands of Arran and Bute, on the west coast of Scotland. The sound leads up from the lower Firth of Clyde and passes the island of Inchmarnock. Then splits into the Kyles of Bute, Loch Fyne and round the north end of island of Arran into the Kilbrannan Sound.
