Armagh is the smallest county in Northern Ireland and one of the most overlooked places on the island. That is a significant oversight. This is the ecclesiastical capital of all Ireland - both Catholic and Church of Ireland Archbishops sit here, which is unique on the island and tells you something about how long this place has mattered. The city itself is handsome, compact, and largely empty of tourists.
South Armagh is a different country again. Slieve Gullion rises out of a ring dyke landscape that is genuinely world-class geology, the Ring of Gullion is one of the best driving loops in Ulster, and the apple orchards of the northern half of the county produce more fruit than anywhere else in Ireland. The county's problem has always been image - decades of Troubles-era headlines mean most visitors, including people from Belfast, have never been. Their loss is your gain.
Know before you go
Armagh is a car county. The city is walkable in an afternoon, but everything beyond it requires wheels. The A28 from the M1 motorway gets you to Armagh city in about an hour from Belfast. South Armagh is accessed via a network of B-roads that are scenic, narrow, and occasionally challenging. The border with the Republic is invisible - you will cross it without noticing.
Below you'll find my complete Armagh intelligence - where to base yourself, what's genuinely worth your time, and the practical stuff that the tourism brochures conveniently skip. Everything from first-hand experience.
