Giant's Causeway

Giant's Causeway, Northern Ireland's UNESCO-listed marvel, is a geological masterpiece of 40,000 interlocking basalt columns formed 60 million years ago by volcanic activity. Steeped in myth as the legendary bridge of Irish giant Finn McCool, this hexagonal wonder—some pillars reaching 12 meters high—creates a surreal, honeycomb-like landscape along the Atlantic coast. A hotspot for geologists and photographers, its symmetry and coastal drama (cliffs, waves, and seabirds) blend science with folklore. This natural stepping-stone to Scotland’s Staffa Island remains one of Earth’s most puzzling and picturesque formations.
