Explore Northern Ireland's Only World Heritage Site
The Giant's Causeway Guide
About 40,000 interlocking hexagonal basalt columns, stretching down to the sea — where science and the legend of Fionn McCool meet on Northern Ireland's north Antrim coast.
Welcome
Explore the Giant's Causeway, a UNESCO World Heritage Site on the north coast of Northern Ireland, in County Antrim. It features about 40,000 interlocking hexagonal basalt columns stretching down to the sea. Legends intertwine with science here: some say these formations are the handiwork of underwater volcanic activity; others recount tales of the giant Fionn McCool, whose exploits shaped the north Antrim coast during a battle with a Scottish giant.
Visitors can use the Dundarave Car Park as a Park and Ride facility inBushmills, enjoying amenities in the village and taking advantage of ticket savings.
At the Giant's Causeway Official Guide, we're passionate about introducing this magnificent natural spectacle to visitors worldwide — informative guided tours for individuals, families, and groups, and everything you need to plan a visit to Northern Ireland's only UNESCO World Heritage Site.
"You are standing on, or are about to visit, one of my favorite places. The jewel in the crown of the fabulous coast of Antrim. A site of World Heritage and therefore ranked alongside Mount Everest and the Giant Redwoods of California for its importance to humankind. Volcanic activity helped Finn McCool forge this wonder of the World some 60 million years ago. It is today the habitat of rare plants and animals. Please treat their home with the pride and the care it deserves."
