River Nairn

[2] The name may involve *Naverna, of which the ultimate genesis is the Celtic root *(s)naf meaning "flow, swim" (c.f.

The headwaters of the Nairn, the Allt Mor and Crom-allt Beag drop steeply down the western slopes of Càrn Ghriogair, their combined waters flowing beneath the B851 road and turning northeastwards.

The River Farnack is the next right bank tributary, followed by the Craggie Burn near the A9 road crossing of the Nairn at Daviot.

Its last major tributary, the Allt Dearg joins from the right and the river continues northeastwards passing beneath the B9090 once again before reaching the town of Nairn.

The Allt Dearg and its major tributary the Riereach Burn rise on the northern slopes of Carn nan Trì Tighearnan and flow north to meet the Nairn.
