River Isla, Moray
The River Isla is a tributary of the River Deveron in North-East Scotland. The area surrounding it is known as Strathisla.
It rises to the northeast of Milltown of Auchindoun and flows northeastwards for 18 miles through Strathisla, separating Keith from Fife-Keith, and then forms the boundary between Moray and Aberdeenshire for a short distance before joining the Deveron near Rothiemay.
The Isla Way is a 13 mile walking route along the river.
