The Lairig Ghru (Scottish Gaelic: Làirig Dhrù) is one of the mountain passes through the Cairngorms of Scotland. The route and mountain pass partially lies on the Mar Lodge Estate. Like many traditional routes, the ends of the route through the Lairig Ghru are like the ends of a frayed rope. From the south the Lairig Ghru can be approached from Braemar though Glen Lui, or Glen Dee, and from Blair Atholl through Glen Tilt. From the north the Lairig Ghru can be approached from Glenmore through the Chalamain Gap, and from Aviemore through the Rothiemurchus Forest by way of the Crossroads above Allt Drùidh.
