The Gap of Dunloe is a narrow mountain pass formed by glacial ice a couple of million of years ago. The valley winds its way for 6 miles (10km) between Macgillycuddy's Reeks and the Purple Mountains. Along the way it passes five lakes, or loughs, Coosaun Lough, Black Lake, Cushnavally Lake, Auger Lake, and Black Lough. The River Loe connects the lakes.
