Airport transportation from and to Dublin Airport
For most of us first touch with Dublin is by the air. Many cheap flights from Ireland based RyanAir bring many tourist to the city. One of the options is to rent-a-car, but if you are not used to drive on the other side, I recommend you Public transport.
From Public Transport- BUS
The Airlink is an express bus that will take you from the airport to the city center, the number 747 is the most frequent and is departing on every 15 min from 5 am to 11-30 pm , in Sunday is till 11-20 pm. Ticket for this bus is €6 for one way and €10 return. For children is €3 single and €5 return.
Also exists the AIRCOACH, it operates 24h and it’s a bit more expensive than the 747.
From Airport to the city by TAXI
Cost can vary €20-25 from the airport to the city center. If you go further than the center is, it will cost you from €30-40. If you decide to use UBER, be in mind that TAXIs are UBERs… (don’t ask me why)
You can also use normal bus to get into Dublin city center, but it will take you a little while, number 16.
Public Transport around the city of Dublin

While the rail service is not extensive, a nice way to see Dublin Bay is to take a trip on the DART (Dublin Area Rapid Transit) suburban train and to travel from the city centre as far as Bray. It's not particularly expensive and you get to see some spectacular views of Dublin Bay. Heading south on the DART, you can stop off at some beautiful villages along the way. For example, Dun Laoire has a beautiful harbour and pier, Killiney has a nice stoney beach and is home to many of Dublin's rich and famous celebrities, Dalkey has a wonderful castle and a gentle village atmosphere, and Bray is a seaside holiday haunt for many generations of Irish families. To the north of the city, the DART terminates at Howth, a quiet fishing village, with some nice cliff walks, and if you're feeling energetic, you can go all the way to the Summit of Howth Head for a spectacular view. Trains run roughly every 15 minutes - for exact times, check the Iarnrod Eireann(Irish Rail) website.
The modern, sleek, almost silent LUAS trams commenced service in Dublin in 2004. There are two lines (unfortunately, there's a 15 minute walk from the Green Line city terminus to the Red Line, but they are building the line connection… hopefully will be finished this year). The route of most interest to the tourist is the Red Line which connects the two main railway stations of Heuston and Connolly. On the way it passes the Four Courts, the rejuvenated Smithfield area, and the National Museum at Collins Barracks; the Green Line runs from St Stephen's Green to the foothills of the Dublin Mountains.
If you are going to spend some days in Ireland, I recommend you the Leap card, it costs €5 and you can top it up any time you need money, you can use the mobile app to do it, and it allows you to save money in many trips, if you are planning to travel very often 100% recommended.
Also, exists different travel cards for families, etc. Consult the website for more information: Dublin Pass.
