DUBLIN: Although the traffic is terrible in Dublin city, the relative lack of an integrated transport network means you'll be getting taxis to get about. The buses are pretty good although they do get caught in the traffic. From the airport there is a special blue Airport bus which takes you into the heart of the city centre. The new light urban rail system, the LUAS, is very popular and easy to navigate, however there are only a couple of lines.
AROUND IRELAND: The vast majority will hire a car to see all corners of the Emerald Isle - see our car rental recommendations. There is also a reasonable train network - for example it is only 2 hours from Dublin to Belfast; check out Irish Rail for details.
