Crainlarich is a village lying about 6 miles northeast of the head of Loch Lomond. The village's name derives from the Gaelic for "low pass", relating to its geographical location.
The village lies in the glen of Strath Fillan at the north western extent of the Trossachs. It is in the shadow of several Munro peaks, notably Ben More, Stob Binnein and Cruach Ardrain. It sits roughly halfway along the West Highland Way.
Crianlarich has been a major crossroads for north and westbound journeys in Scotland since mediaeval times. It is served by its own railway station.
