For mainland UK residents, flying into Belfast is the fastest way to experience the dramatic Causeway Coastal Route (including the Giant’s Causeway, Carrick-a-Rede Rope Bridge, and the Glens of Antrim) and the Mourne Mountains.

Driving Across the Border into the Republic of Ireland
Because there is no hard border between Northern Ireland and the Republic of Ireland, many travelers pick up a car in Belfast and drive south to Dublin, Galway, or Donegal. If you plan to cross the border:
- Notify Your Supplier: You must check the Cross-Border Policy in the rental terms. Most companies permit cross-border travel for a nominal insurance fee (typically £25 to £35 per rental).
- Speed Limits & Road Signs: Northern Ireland uses Miles per Hour (MPH) and Pounds (£). Once you cross into the Republic of Ireland, speed limits switch to Kilometres per Hour (KM/H) and currency switches to Euros (€).
