passport

Do I need a passport if I am travelling to southern Ireland by ferry?

If you're British then, yes you do as it is a foreign country.

UK citizens do not require a passport or visa to enter Ireland, however most carriers by air or sea now require some form of identification with photograph, usually a passport or driving license with photo.

Visitors should check what form of ID is required with the individual airline, ferry company or travel agent before travelling.

Depends where you're from. If you're British then no, although as mentioned it's a good idea to have some form of official photo ID. When I was there about 4 years back there wasn't anyone manning customs either end.

If you're from outside the UK it'd be an idea, although I think it's basically classed as an internal connection so they assume if you got into the UK then you're legit.

Oh and as a sidenote, if you're not driving - enjoy the bus ride into the town, it's an "experience". :)
