Dublin Airport is located a mere 10 kilometres north of Dublin city centre, so transfers are easily arranged. The terminal lies near the crossroads of the M1 and M50 motorways, and the ride takes around 30 minutes outside of rush hour. The most convenient way to get back and forth is with cheap car hire in Dublin Airport, but there are several other options available. Traffic can be an issue, so it's worth arriving at off-peak hours if you have any say in the matter.
Whether you've arranged Dublin Airport car rentalor have a friend in town who doesn't mind picking you up, it's easiest getting to and from the terminal by car. Passengers can be picked up and dropped off immediately outside the terminal, but waiting isn't allowed.
Dublin Airport also has 3,600 short-term parking spots in the car-park adjacent to the terminal. Of course, with a rental car you only need to drive to the drop-off point so that the attendants can shuttle you to the terminal entrance. Four times as many long-term spaces are available.
Roughly 700 buses serve Dublin Airport each day, connecting across County Dublin and its surrounding suburbs on fixed routes. Airlink and Aircoach connect from the Arrivals Hall to key areas across Dublin, including bus and railway stations.
