The airport is on the northern edge of the city. The easiest way to get into town is to take a taxi, this should cost about 25 EUR. Irish people don't routinely tip taxi drivers, though they will sometimes round up the fare. There are two express buses which bring you straight into town, the 747/748 is a Dublin Bus service and will bring you as far as Busarus, the central bus station. Busarus is just north of the Liffey on Amien Street and is marked on the city center map. This cost 4.50 EUR. The Aircoach costs 5 EUR and goes through the city centre and down past Stephen's Green. Finally, the Aerdart connects with the DART, a light rail running along the Dublin coast. This is useful if you are going to somewhere in the south of the city, but too elaborate if you just want to go to the city center.

The main tourist office is on Suffolk Street near Trinity, it is marked with a blue i on the City Center map. There is also an official tourist web site.
