Giants Causeway Tour
The Giant’s Causeway is almost 60 million years in the making and counting. Find out how the world-famous hexagonal basalt stones were formed, and discover the legend of the giant who made the causeway – but was it for love or battle?
The making of the Giant’s Causeway
The Giant’s Causeway formed just under 60 million years ago, and at that time Ireland was still attached to North America. Europe was starting to rip away from North America, and as it did so it created huge rifts in the earth’s surface. Those rifts produced cracks, and up through those cracks came lots of molten rock and lava.
Much later, erosion then caused rivers to form in the basalt. Then more lava came, which flowed through the river valleys. In this river valley, the Giant’s Causeway we think of today was formed.
