The “Inishowen 100″ is one of Ireland’s most scenic drives. Its a 100-mile (160km) circular route around the Inishowen Peninsula in North East Donegal. Bounded on three sides by water, the peninsula is almost triangular in shape, between Lough Foyle and Lough Swilly and bordered by the Atlantic Ocean to the north.
With splendid coastal scenery plus a good collection of ancient forts and monuments, traditional craft centres, and a dozen or so friendly villages, many people consider Inishowen to be a miniature Donegal.
Scenic highlights include the breathtaking Gap of Mamore, a scenic roadway that rises to a height of 800 feet above sea level before following a twisting corkscrew descent with panoramic views of the entire northern coastline; Malin Head, Ireland’s most northerly point; and Fort Dunree – a magnificent viewing outpost.
