County Antrim stretches from Belfast north to the iconic Giant’s Causeway and includes the Causeway Coastal Road. The Giant’s Causeway is a UNESCO Heritage Site, and the Glens of Antrim are also famed for their rugged beauty. Antrim is the most populous county in Northern Ireland, with a large portion living in Belfast, but there are numerous coastal villages and market towns in the county with their own distinct characters. The area has good air, rail, and sea links, including Belfast International Airport, the Translink Northern Ireland Railways routes, and ferries from Larne Harbour to England and Scotland.
