The Giants Causeway is a natural phenomenon which was formed 60 million years ago by volcanic activity. Ten thousands of basalt columns are rising from the sea. As well as the site there is also a Visitors Centre where one can watch audio-visual presentations about the Giants Causeway, a coffee shop, bureau de change and a souvenir shop.
In 1986 the Giants' Causeway was declared a World Heritage Site by the UNESCO.
The site can be reached by car, by train or by bus. The Center is open daily from 10.00 - 17.00 (closes at 16.30 November - February).
