Lies in the north coast of NI
It is an impressive formation of some 40,000 basalt columns descending like a giant staircase into the sea.
According to the legend the columns are the start of a causeway constructed by the terrible Irish Giat Finn MacCool in attempt to cross the sea to the Scottish coast.
