Bus Eireann

Because of the aforementioned traffic Dublin Bus isn't very reliable on its timetable. Thereare stops everywhere, they are blue, usually with the numbers of bus that stops written on them. There is usually a helpful dublin bus employee hanging around somewhere on the street, in a navy uniform with a peaked hat. Otherwise check out timetables and destinations on dublinbus.ie

You can buy prepaid tickets which you validate at the front of the bus when you get on or you pay the driver by putting the exact change in the box in front of him. He won't give you change, instead a receipt that can be redeemed at Dublin Bus headquarters on O'Connell Street, as if you're going to do that, so whatever you do have change... don't go putting 5 euro notes in there!! Usual international bus rules apply: give your seat to an old person or someone else who needs it, don't block the aisles and don't talk to the driver while the bus is moving!!
