The Ring of Gullion
The Ring of Gullion is a real geological curiosity! It's a group of volcanic hills that have eroded over time. Together, they form a veritable "circle" several kilometers in diameter. A little extra: the Slieve Guillon sits right in the middle of the ring! <a href="https://www.go-to-ireland.com/what-to-see/the-ring-of-gullion/">[...]</a>
