Beinn Chùirn is a Scottish hill situated five kilometres west-southwest of Tyndrum, it stands on the border of Stirlingshire and Perthshire at the northern extremity of the Loch Lomond and the Trossachs National Park. Beinn Chùirn reaches a height of 880 metres (2887 feet) and qualifies as a Corbett and a Marilyn. It stands in the Cononish valley in the company of three other mountains (Ben Lui, Ben Oss and Beinn Dubhchraig which are all Munros and tend to overshadow the smaller hill. When seen from the east Beinn Chùirn looks like a smaller version of the neighbouring Ben Lui, both having impressive east facing corries, it is sometimes mistaken for Lui by motorists on the A82 road in Strath Fillan. The hills name translates from the Gaelic language as “Cairn Hill”. In recent years the hill has received some publicity after the discovery of a vein of gold on its slopes.
Beinn Chùirn has quite a high Topographic prominence of 446 metres being surrounded by glens and low cols. To the north is Glen Lochy and to the south is the Cononish valley. Two km to the east lies another Marilyn hill Meall Odhar to which it is connected by a col of 473 metres, while three km to the south west lies the Munro Ben Lui across a col of 434 metres. The hill has a fine east facing corrie, Coire na Saobhaidhe, which is small but has steep walls. Just north of the summit at a height of 810 metres is an unnamed circular lochan about 100 metres in diameter.
