About Croslieve

Rising as a rugged outpost of the Ring of Gullion, this heather-clad summit offers an accessible but rewarding climb. Despite its modest height, its isolation provides a sense of wildness, with a rocky top that overlooks the volcanic landscape of South Armagh and the sweeping coastal plains towards Dundalk Bay.

• •The name is derived from the Irish 'Crois Shléibhe', meaning 'Mountain of the Cross', likely signifying its historical importance as a landmark or religious site within the early Christian landscape of the Armagh borderlands.
• •The hill is a key feature of the Ring of Gullion, a unique geological formation where a series of hills forms a circle around the Slieve Gullion caldera, created by a volcanic ring dyke millions of years ago.
• •From the summit, walkers are rewarded with clear views across the gap into the Cooley Peninsula to see the sharp profile of Slieve Foye, while the granite peaks of the Mourne Mountains are visible to the east.
• •Although relatively low at 308 metres, its status as a Marilyn—a hill with at least 150 metres of prominence—means it stands significantly higher than the surrounding terrain, offering a more 'mountainous' feel than its elevation suggests.
• •Standing at 1,010 feet, the hill exerts exactly the minimum amount of effort required to maintain a four-figure height, narrowly avoiding the ignominy of being a mere three-digit hill.
