Cairnsmore of Fleet is an isolated hill, part of the Southern Uplands of Scotland. The mountain forms an unafforested granite massif, whose highest point is about east of Newton Stewart. It is the highest of the Solway Hills sub-range, and the southernmost of Scotland's 219 Grahams, thus making it, or rather its subsidiary top, Knee of Cairnsmore, the most southerly mountain in Scotland. The view to the south takes in the Cree Estuary and Wigtown Bay, and extends as far as the Lake District, the Isle of Man and Snowdonia. The highest summits of the Galloway Hills can be seen to the north, and Ireland is in the view to the west.
