At the end of the Dingle Peninsula lies the picturesque area you see above, Dunmore Head, the westernmost point of Ireland (excluding the islands). The photograph was taken by Bjørn Christian Tørrissen from Slea Head.

The peninsula is named after the town of Dingle but is also commonly called Corca Dhuibhne (Corcu Duibne). 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. The Conor Pass, which runs from Dingle on the southern end of the peninsula towards Brandon Bay and Castlegregory in the North, is the highest mountain pass in Ireland. [Source]
