Dublin City is served by a number of city bus routes and a tram system, the Luas (or the “Jerry Lee” as the local Dubliners call it) and there is a wealth of taxis on the streets but you really will not need to use these services in the city centre. Dublin is a nicely compact city so everything is within walking distance, the centre is easily navigable by map and locals are super-friendly and happy to give directions. Take note however that should you opt for a bus at some point you pay the fare by dropping coins into the slot in front of the driver's window and rember that change is not given, so best to have exact fare. The Luas is handy for getting to and from The Guinness Storehouse, Museum of Modern Art, the National Museum of Decorative Arts and Connolly & Heuston train station. You must purchase a ticket before boarding at the touch-screen ticket machines at Luas stops. They are patrolled regularly by ticket inspectors and you're likely to face a hefty fine if you're caught without a ticket.
