County Louth

Ireland's smallest county holds an outsized share of the story: high crosses at Monasterboice, the Boyne Valley at its south and the Cooley Peninsula for mountains and the lough. Dublin and Belfast are both an easy drive.

County Louth

County Louth facts

Ireland's smallest county holds an outsized share of the island's history. The Boyne Valley reaches into its south around Drogheda, Monasterboice preserves some of Ireland's finest high crosses, and Mellifont was the country's first Cistercian abbey.

The Cooley Peninsula in the north is Louth's scenic heart, a mountainous finger of land between Carlingford Lough and Dundalk Bay, linked to the Táin Bó Cúailnge, Ireland's great epic. Carlingford itself, a medieval coastal town with castles and oyster fame, is the county's best-known destination, while Dundalk serves as its working county town. Its position on the Dublin–Belfast corridor makes Louth an easy add-on, but it deserves more than a pass-through: a night in Carlingford, with dinner overlooking the lough and a walk on Slieve Foy the next morning, is a trip highlight in itself.
