Northern Ireland: the Giant's Causeway

In 1986, UNESCO named Ireland's first World Heritage Site: the Giant's Causeway, a mysterious geological formation on the North-Eastern coast of Ireland. 
The site is an area of approximately 40,000 interlocking, hexagonal basalt columns that are neatly packed together and form a jagged headland which points towards Scotland. 
Visitors can walk along the columns as they form stepping stones that disappear downward into the sea. 
Science, myth and legend surround the Giant's Causway, the latter of which is the most colorful. It is said that the Causeway was the stomping ground of a giant who lived in the area two thousand years ago. Perhaps you may discover the chimney to one of his houses or the boot he left lying by the beach?
In the newly opened Visitor's Center you learn that, according to geologists, the site is believed to have been formed some 50-60 million years ago and is the result of an ancient volcanic eruption.
Often described as the Eighth Wonder of the World, the Giant's Causeway was documented as early as 1693 and realistic sketches of the site were published in 1740. 
Not far from the Giant's Causeway, you will also find the Carrick-a-rede Rope Bridge. Traditionally the bridge was erected by fishermen over a 75-foot deep and 66-foot wide chasm in order to check their salmon nets. 
Anyone brave enough to cross is sure to be rewarded with a fantastic view.
