An Extraordinary Geological Legacy
On Northern Ireland’s Antrim coast, ancient basalt forms a remarkable pattern of columns beneath cliffs and open sea. Cooling lava and later erosion created a landscape celebrated for both beauty and geological insight.
Inscribed by UNESCO in 1986, the Causeway connects deep time with stories of Finn McCool. Explore its formations and coastal paths thoughtfully, with weather, footing and current site guidance shaping the visit.
