If you're visiting Dublin from England, Scotland or Wales, you'll need to cross the Irish Sea to get there. There are two ways to get to Dublin: by flight or by ferry. You can fly to Dublin Airport from all over the UK, with Ryanair, British Airways, Aer Lingus and other operators carrying you over the water for £ 100 or less. Alternatively, you could hop on the ferry from Liverpool, Holyhead or Douglas. The fastest crossing is Holyhead to Dublin. Take your car or leave it behind - it's just over five kilometers from Dublin ferry port to the city center, so hop in a taxi or take the 53 bus.
