The Giant's Causeway is one of Ireland's most unusual natural wonders. It's been estimated that approximately 37,000 basalt columns extend from the cliffs down to the sea. Those closest to the shore have been eroded to form the Grand Causeway, Middle Causeway and Little Causeway as well as Chimney Stacks and the Wishing Chair, which is a part of the Middle Causeway.

The Wishing Chair is said to have been made by legendary Finn Macool who, when he was a boy, used to sit here to look out to see, and the coast of Scotland. Local legend says that anyone who makes a wish while sitting in the Wishing Chair will have it come true!

Basalt columns were created about 61 million years ago during a series of volcanic eruptions. Layers of solidified lava cooled rapidly, in the process shrinking and cracking evenly into these polygonal-shaped blocks, that average 12 inches across; most are hexagonal but others have up to ten sides.

It was the end of the last ice age, when the land was frozen, that the shore as we see it today was formed.

There is an interpretive center here with gift shop and cafe. A shuttle bus will take passengers down to the site, which is at the bottom of a very steep road.
