Lairig an Laoigh

The Lairig an Laoigh (/ˈlɑːrɪɡ ən ˈluːi/ LAR-ig ən LOO-ee; Scottish Gaelic: Làirig Laoigh) is a mountain pass through the Highlands of Scotland. In speech and sometimes in writing the name is reduced to "Lairig Laoigh". It is of glacial origin, dissecting the Cairngorm plateau, and it runs roughly north–south from Speyside to Deeside at one time being used as a drove road. Between the public road in the Abernethy Forest and the one at Linn of Dee the trekking distance is 31 kilometres (19 mi).

The name Lairig an Laoigh means "pass of Lui" or possibly "pass of the calves". In its southerly part it lies in the Mar Lodge Estate, owned by the National Trust for Scotland where Derry Burn flows into Lui Water, a tributary of the River Dee. The northern part is in the Abernethy Estate, owned by the Royal Society for the Protection of Birds where the River Nethy flows north to the River Spey. The whole area is in the Cairngorms National Park.
