To and From Dublin Airport, Dublin

There are three different buses from Dublin Airport to the centre. One was 10euro, one 6euro and one 2euro. They differ in terms of comfort and time. The 2 euro bus was number 16 and is located outside the arrivals terminal exit. You can buy your ticket from either a machine or from the driver (exact change needed). It took about 30 minutes to get to O'Connell Street from departure.

From the airport take the 747 bus to get to the downtown area of Dublin off of O'Connell street. The buses are green and can take you to the airport as well. Each way is 6 Euros, which is the best deal you'll get in travel. To find the nearest bus stop to your hotel, just ask reception and they'll know.

Getting to and from Dublin Airport must be unique in Europe.
There's an "Aircoach" that is excellent. It serves South Dublin much better than North Dublin.
Timetable and drop off / pick points can be see at

There's an "Airlink", run by Dublin Bus that's very limited. Hardly surprising! Serves the Bus Station ( for buses throughout Ireland) and some of the rail stations ( for trains throughout Ireland). Not much use if your plans were to visit Dublin. The Bus Station is not in the most pleasant part of the City and the Rail Stations were built in the 19th Century, more with military / strategic objectives than convenience for a travelling populace and are for from central Dublin
Now here's a paradox.
You can also get a taxi. There always seems to be plenty of taxis at Dublin Airport and its reasonably quick however it is quite expensive. Allow 25 to 30 Euro for you journey to the north City or City centre and possibly 30 to 40 Euro to the south City.
Getting back to Dublin Airport is very difficult.
If you are convenient to a pick up point for the Aircoach, you can hardly do better.
Otherwise a taxi is probably the best, however if you try to book a taxi, early in the morning or during rush hour you might find a very negative attitude. Just keep phoning different "taxi companies" in the hope you will get a booking. You probably will, eventually.
If you're staying in a good hotel, they will probably have a taxi company they can call on with reliability, so ask the hotel to book one.

The bus to dublin airport is easy
It takes just over half an hour and cost me 6euro. you just queue up and pay the bus driver. i got the bus from Heuston train station, it comes everyhalf hour. there are other places, including Connolly Street (this did seem v busy tho)

Airlink is the bus service offered by DublinBus to and from the Airport. It cost €6 one way or €10 round trip and is also included in the Rambler tickets.
There are other Dublin Buses that provide service to and from the Airport (such as the 16) but Airlink 747 is non-stop between the Airport and O'Connell St. and then to Connelly Station. Going to the Airport it also stops at Parnell Sq. West.
The Airlink bus 748 makes a few more stops but all in it is a quick convienent way to get from the airport to Dublin's center.

Take the 16A bus to O'Connell Street. It drops you right next to the spire and was a little quicker than the guide book made out. About 30-40 minutes.

It was only 1.6euros, the Airlink buses cost nearly 5euros are aren't much quicker!

Dublin Airport is about 7 miles or 10k north of the city. Dublin bus runs a special Airlink bus into the city centre every 10 minutes during the week and every 20 minutes during weekends. The cost is €6.50 each way. The bus departs outside the arrivals hall. Go to the information desk before you leave the airport terminal. The Airlink also stops in Busaras which is the main terminal for provincial buses. Connelly station is near Busaras as is the DART Dublin Area Rapid Transport. The Airlink will also drop you off at Heuston Station the mainline rail station which serves the south and west. You can also catch a normal double decker bus number 41 from outside the arrivals hall. The cost is around €2.20 and will drop you in the city centre. It takes a bit longer but if your on a budget take this option. You can also catch a cab again outside the arrivals hall. The cost is high and they charge you for almost everything, from your bags, to the time of day. No set charge like New York.. Please be careful l have heard many sad stories of taxi men ripping off tourists.. take the bus instead. If don't have a rail system that takes you to the airport.. not yet...

Aircoach bus stops are right outside the arrival exit. They have several destinations, i.e., Cork, Belfast and Portaoise, so ask the ticketing staff where the Dublin City Centre bus stop is. The bus leaves every 10-20 min.
The ticket is 7euro one way, and 12 euro return. You can buy a ticket at the stops or online.

The bus to Dublin City Centre makes several stops including O'Connell St., near the Trinity College, and near the St. Stephen Green. Check online for route information to see which stop is close to your destination/hotel.

You can get on the bus to the airport in front of the Dublin Tourism Office on Suffolk St.

There are 3 ways you can get to your hotel from the airport - taxi, the airport shuttle bus, or the regular city bus. If you value you money like I do, TAKE THE CITY BUS. We were quoted about 30 Euros for a taxi, and 6 Euros each for the airport shuttle. The bus picked us up right outside the airport and dropped us out right outside our hostel in temple bar for 1.30 each!!! There was even someone on the bus to load our luggage and tell us what stop we needed to get off at! If you need to know what bus to take, just ask at the tourist office in Dublin Airport - the bus stop is right outside their door.
