About Giant's Causeway
Famed around the world for its columns of layered basalt, the Giant's Causeway is Northern Ireland's only UNESCO World Heritage Site. These polygonal-shaped natural features (there are around 40,000 of them) were created by a volcanic eruption 60 million years ago. Today, they are the prime focus of a designated Area of Outstanding Natural Beauty.
Naturally, most visitors' first stop along this scenic coast is the World Heritage-listed Giant's Causeway. The surrounding coastline, however, is magnificent and shouldn't be bypassed, such as the ruins of Dunluce Castle, only 10 minutes drive west along the picturesque coastal road.
