About Ulster

Ulster is made up of six counties in Northern Ireland (Antrim, Armagh, Derry, Down, Fermanagh, and Tyrone) and three counties in the Republic of Ireland (Cavan, Donegal and Monaghan).


The province’s highest point, Slieve Donard (848 metres (2,782 ft)), stands in County Down. The most northerly point in Ireland, Malin Head, is in County Donegal, as are the sixth-highest (601 metres (1,972 ft)) sea cliffs in Europe, at Slieve League, and the province’s largest island, Arranmore. The most easterly point in Ireland is also in Ulster, in County Down.
