The Dingle Peninsula (Irish: Corca Dhuibhne; anglicised as Corkaguiny, the name of the corresponding barony) is the northernmost of the major peninsulas in County Kerry. It ends beyond the town of Dingle at Dunmore Head, the westernmost point of Ireland and arguably Europe.
The Dingle Peninsula is named after the town of Dingle. The peninsula is also commonly called Corca Dhuibhne (Corcu Duibne) even when those referring to it are speaking in English. Corca Dhuibhne, which means "seed or tribe of Duibhne" (an Irish personal name), takes its name from the túath (people, nation) of Corco Dhuibhne who occupied the peninsula in the Middle Ages and who also held a number of territories in the south and east of County Kerry.
The peninsula exists because of the band of sandstone rock that forms the Slieve Mish mountain range at the neck of the peninsula, in the east, and the unnamed central mountain range further to the west. Ireland's highest mountain outside Macgillycuddy's Reeks, Mount Brandon at 951 m, forms part of a beautiful high ridge with stunning views over the peninsula and North Kerry.
Conor Pass, which runs from Dingle on the south-western end of the peninsula towards Brandon Bay and Castlegregory in the north-east, is the highest mountain pass in Ireland, a narrow, twisting road; it weaves its way around the sharp cliff faces and past the high corrie lakes.
