Transportation in Dublin
Walking is the best way to explore the relatively compact city, so wear comfortable (and waterproof!) shoes. The tourist office on Suffolk Street provides a decent street map, and places of interest are well sign-posted.
It's usually easy to find a taxi, either by flagging one down in the city centre or booking one in outer areas. They all run on meters so beware of sitting in heavy rush hour traffic with the euros clocking up.
Dublin's modernised network of buses criss-crosses the city centre, with most routes passing close to Trinity College. Pay the driver on entry and if in doubt of your whereabouts, chatty passengers will help you out. There are a variety of airport buses available, and a limited number of night buses. Timetables are usually posted at the bus stops. An lar is Gaelic for "city centre".
Rent your car
The M1 leads straight into Dublin from the north, connects with the M50 outer ring, or continues underground through Dublin Port Tunnel for ferry connections and south Dublin. They all charge tolls. A SmartPark Card allows you to park at Q-Park's city centre car parks overnight from €6.40.
A Dublin Pass Rambler Ticket offers unlimited bus travel over one, three or five consecutive days. It includes the airport bus, so buy one at the airport. Pre-paid, one-day DART tickets usually work out cheaper than cash fares. Avoid rush hour, when streets are clogged with cars, and leave plenty of time to reach the airport, especially in the early evening and at weekends after a match (of Gaelic football, hurling, or anything!)
