The Campsie Fells are a range of hills in central Scotland, stretching east to west, from Denny Muir to Dumgoyne, in Stirlingshire. (The southern extent of the range fall within East Dunbartonshire). The highest point in the range is Earl's Seat which is 578 m (1897 feet) high. The range overlooks the villages of Strathblane, Blanefield and Lennoxtown to the South, Killearn to the West and Fintry to the North. The Fintry Hills lie further to the North, Kilpatrick Hills lie to the West and the Kilsyth Hills to the east.
The name is taken from one of the individual hills in the range, called Campsie; meaning crooked fairy hill, from the Scottish Gaelic cam, meaning crooked, and sìth meaning fairy. Fells originates from the Old Norse word fjal, meaning hill.
Erosion along the line of a geological fault known as the Campsie Fault has left tiers of rock representing some 30 lava flows which date from the Carboniferous period.
The headwaters of the Carron rise in the Campsies.
