Giant’s Causeway

The Giant’s Causeway is a World Heritage Site, National Nature Reserve and Northern Ireland'spremier tourist attraction. It is made up of some 40,000 massive black basalt columns sticking out of the sea. Formed between 50 and 60 million years ago, takes its name from the legends of Finn MacCool. Known to the Irish as the 8th Wonder of the World.

There are 15 miles of footpaths along the Causeway Coastline, owned and maintained by the National Trust. The formation of the Giant’s Causeway was due to intense volcanic activity. Lava welling up through fissures in the chalk bed formed a -lava plateau.

Within the nature reserve, a series of paths run between the visitor centre at Causeway Head and Hamilton’s Seat. Most of the columns are hexagonal, although there are also some with four, five, seven and eight sides, the tallest are about 12 metres.

Sea birds can be seen off the coast around the Causeway, with species such as fulmar, petrel, cormorant, shag, redshank guillemot and razorbill being frequently observed.
