To Dublin From the Airport
Dublin is served by Dublin International Airport, which is located north of Dublin City Centre. There are frequent connecting buses from the airport to the city centre, including a special shuttle service, Airlink which brings passengers directly to Busáras (Central Bus Station, Dublin).
Aircoach operates a service from Dublin Airport to Leopardstown / Sandyford / Stillorgan which passes UCD.
From Dublin to UCD
Most of you will be arriving from Dublin city centre, and the easiest way to get to UCD’s Belfield campus is to take a city bus. The 46A, 145, and 39A buses go through the centre of town and come directly to campus. Timetables are more suggestions than schedules, and buses can be quite busy around rush hour times. From the city centre, leave yourself at least 45 minutes to catch a bus and find your way across the UCD campus.
NB: All Dublin Bus buses have wifi.
Catching a bus
Have loose change, as the bus doesn’t accept bills, and you’ll need to pay with exact change. Just tell the driver you are going to UCD, and she or he will tell you the fare. From city centre, the cash fare is €2.85. You can plan your journey on http://www.dublinbus.ie/
Arriving at UCD
The 39A bus terminates at UCD, so no need to worry about getting off at the right stop. If you catch the 46A or 145, just press one of the red stop buttons when the electronic sign on the bus says UCD, or ask the driver to point out the campus. Many people get off at campus; you won’t miss it.
Both the 46A and the 145 set down on Stillorgan road. With your back to the bus, walk toward the overpass you’ve just passed. You’ll turn left at the light, cross the overpass/bridge over the motorway and be on campus. You will be able to follow the crowd.
Taxis are very easy to hail in town or from one of many taxi stands on main streets or in front of hotels. If you need to pay by card, be sure to ask the driver before you get in whether she or he accepts cards.
If you like pay-by-phone apps, MyTaxi is the most prominent one in Dublin. You can download it, add a credit card, and call a taxi anywhere that your phone is internet connected.
Avoid driving to campus if at all possible. Parking is extremely tight, though there are a few spots available for 3 Euro per day. For driving and parking directions, see here: http://www.ucd.ie/humanities/about/wheretofindus/
