Across the Border
Northern Ireland — part of the United Kingdom — is accessible from Dublin without passport formalities for EU/EEA citizens (carry ID). The border is unmarked on major roads. Northern Ireland’s attractions include the Giant’s Causeway, Belfast (the Titanic Quarter, the political murals, the Victorian architecture), the Antrim coast (Carrick-a-Rede rope bridge, the Glens of Antrim), the Dark Hedges (Game of Thrones), and Dunluce Castle.
Day tours from Dublin to Northern Ireland typically combine the Giant’s Causeway with the Antrim coast and sometimes Belfast, running 12–14 hours. The cultural contrast — different currency (sterling), different political history, different atmosphere — adds a dimension that purely Republic of Ireland tours do not.
