About Slieve Gullion
Slieve Gullion is the high point of County Armagh and the core of the Ring of Gullion, dominating the country around it. On a clear day the outlook reaches County Antrim in one direction and Dublin Bay and County Wicklow in the other.
The summit holds a small lake and two ancient burial cairns, one of them the highest surviving passage grave in Ireland. The mountain runs through Irish mythology, linked with the Cailleach and with Fionn mac Cumhaill and Cu Chulainn.
Slieve Gullion Forest Park lies on the eastern slope, and villages including Meigh, Drumintee, Forkhill, Mullaghbawn and Lislea ring the hill. Its name has spread to the surrounding countryside and to an electoral area of Newry, Mourne and Down District Council.
