Explore the Ring of Gullion: South Armagh's Mythical Landscape

This Area of Outstanding Natural Beauty encompasses a ring dyke—a unique volcanic formation—surrounding the central peak of Slieve Gullion (573m). The landscape combines dramatic mountain scenery, ancient forests, mysterious lakes, and some of Ireland's most significant prehistoric monuments.
