Situated on the North coast of Ireland, the Giant’s Causeway is an area of approximately 40,000 interlocking basalt columns, the result of an ancient volcanic eruption. The Giant’s Causeway has often been described as the Eighth Wonder of the World and was declared as Ireland’s first World Heritage site by UNESCO in 1986. Once you have visited, you will quickly see why it has become Ireland’s top tourist attraction.
The spectacular coastal scenery of the Giant’s Causeway is formed by surface outcrops which are entirely in the Tertiary Basalts. The cliff-like edge of the plateau, the varied structure and colour of the basalts and inter-basaltic beds and the subsequent differential erosion of the different rock and soil types have resulted in a unique arrangement of features which are of outstanding scenic quality and geological interest.
