5. Giant’s Causeway
Ireland has a lot for a tourist to see as the country is rated as one of the top tourist destinations in the world. While you will never see everything worth seeing in Ireland, one of the most critical stops on your next vacation is the Giant’s Causeway in Northern Ireland.
Declared a national nature reserve in 1987 and a World Heritage Site by UNESCO the year before, the structure is unique and unlike any other in the world. It’s made up of about 40,000 interlocking basalt columns as high as 39 feet created from an ancient volcanic fissure eruption.
