The A9 road passes through here, as does the Highland Main Line, the railway between Inverness and the south of Scotland.
The pass is the only gap in the main Grampian Watershed suitable for road traffic routes for almost 100 km, between Glen Coe (west) and Cairnwell Pass (east); the West Highland Railway is the only other crossing, at Corrour.
There are routine winter patrols from November to March, and the road is occasionally closed with snow gates near Dalwhinnie and Dalnacardoch.
It is isolated, and the nearest settlement of any size is the small village of Dalwhinnie, some 10 km (6 mi) to the north.
The summit of the pass marks the boundary between Perth and Kinross and the Highland Council area.
