Giant’s Causeway UNESCO World Heritage Site

Basalt columns, Atlantic cliffs, and coastal landscapes on Northern Ireland's north coast

The Giant's Causeway UNESCO World Heritage Site sits on the Causeway Coast of Northern Ireland, where thousands of interlocking basalt columns extend from the cliffs into the North Atlantic. Formed by volcanic activity millions of years ago, the site contains one of the world's most distinctive geological landscapes and remains one of the most recognisable natural landmarks on the island of Ireland.

Located within the Causeway Coast National Landscape and connected to the Causeway Coast Way, the site forms part of a wider network of routes, landscapes, and places along Northern Ireland's north coast. Today, the Giant's Causeway links coastal cliffs, geological features, and walking routes across one of the region's most significant protected landscapes.
