The Giant’s Causeway (Clochán na bhFomhóraigh in Irish) is one of Northern Ireland’s most popular visitor attractions, with over a million visitors each year. The Causeway is a naturally occurring area of basalt columns, which were created by volcanic activity but look as though they were built on purpose. As a result, the Causeway has featured in Irish myths and legends for hundreds of years. Visit alone or as part of a day trip from Belfast or Dublin.
