The Galloway hills are part of the Southern Uplands of Scotland, and form the northern boundary of western Galloway. They lie within the bounds of Galloway Forest Park, an area of some 300 square miles (800 km2) of largely uninhabited wild land, managed by the Forestry Commission. The unusual place names reflect a mixture of the Old Norse and Scottish Gaelic languages and hint at the range of influences which have acted on society within the area over the centuries.
The location of Galloway is described as follows, "Galloway is contained by sea to the west (North Channel) and south (Solway Firth), the "Galloway Hills" to the north, and the River Nith to the east". So if we were to say "The hills of Galloway" we would be including all the hills within this area; but as the first sentence implies the "Galloway hills" is usually taken to mean a collection of ranges which lie mainly south of Loch Doon and which are not constrained by political boundaries. The boundary between Dumfries and Galloway Region and Ayrshire in Strathclyde Region runs west to east over Kirriereoch hill, drops south of Mullwharchar to the shores of Loch Enoch, before heading northwards up the east shore of Loch Doon, and so runs more or less through what might well be considered the heart of the Galloway hills - around Loch Enoch.
The northern limit of this hill area is around the small towns of Dalmellington and Straiton, both in Ayrshire. The B741 runs on an east/west line between these two towns on its way to the town of Girvan on the Firth of Clyde. So the B741 could therefore be taken as the northern limit of the Galloway hills area. From Straiton a minor road (no name on the Ordnance Survey map) runs south by Stinchar Bridge through the north west corner of these hills to meet another minor road which runs from Glentrool village northwards towards Girvan and Maybole. This latter road forms the western boundary of the Galloway hills. It follows the valley of Water of Minnoch and for most of its length it passes through the extensive forestry plantations which lie to the west of the Galloway hills.
