We flew into Dublin for a day, just a short adventure to see what we could see. On arrival at the airport, we went to the tourist desk who gave us two options for getting to the city centre - either as part of the Dublin pass which would also include entry to various attractions but would only take us there and not back, and would cost 29 Euros each. The other option was on the regular bus, two adults could travel return on a family ticket for 8 Euros 50. Guess which one we went for? :)
The bus to the city centre is the 747 and stops directly outside the terminal, and takes you to O'Connell Street (which I must say isn't the smartest area I've ever seen). We had no luggage so this was absolutely no fuss whatsoever. There was only a short wait for the bus each way and the journey took about half an hour to 40 minutes. At 8.50 for two adults you can't grumble at the price either.
The local transportation in Dublin can be a problem, especially in crowded hours. Buses are infrequent, they tend not to respect the schedule, and the trip-fare is expensive compared to the quality of the service. The city needs a subway or at least the extension of the tram network.
Except walking or biking probably teh cheapest way to travel around Dublin...I found the bus drivers to be rude and unhelpful for the most part. I asked one driver to let me off near Camden and he told me to get off near Trinity College...I ended up having to walk a good 15-20mins with my backpack. A couple of other times when I asked if they would let me know when my stop arrived, I got the answer 'if i remember' rudely.
EXACT CHANGE. Don't try and expect change from the driver coz he won't have it. you need to have exact change. it's between 0.85 Euro and 2.65 Euro per trip. You can get travel tickets, in some shops and at dublin bus on o'connell street (main street), but unless your doing alot of traviling accorss town don't bother. just keep a suply of 1, 0.50, 0.20, 0.10, 0.05 Euro coints in your pocket.
Now you can get on as state your destination (make sure that you on the right bus) or the price. shorter journeys are 0.85 Euros to 2.65 Euros for longer journeys.
Inspectors can get on the bus and check your tickets so be careful about trying to cheat and the penalties are harsh.
Buses stop around 11.30pm and from monday to saterday there is nightlinks, they cost from 4.00 to 6.00 Euros for a one way journey, but it's better than taxies.
Dublin has quite a good Bus Service. Integrated tickets are not available yet but they are on the way. More info can be found on their web site. Just put in where you want to go and the bus numbers that service the area will be shown. You can the look up the time-table on the second link.
Do not get the 16A bus to or from Dublin Airport...it goes all around the world, picks up little old ladies and drops them off again before it hits the city centre. Definitely not if you're in a rush.
Bus is the only way to do it in Dublin. Service is quite good during the day, but be careful not to the miss the last bus at night. There is a NiteLink for those out until the wee hours, but this service is more limited and more costly.
Coming from Germany the public transport system in Dublin took some getting used to. For one thing the timetables only show when the bus leaves at its starting point, and when it arrives at the terminus is anyone's guess. Due to the pretty much congested city centre it is impossible to predict the arrival times at any of the stops, anyway. It happened to me more than once that I had to wait for more than an hour for a bus that is supposed to run at 20 min intervals.
Also, bus drivers will not necessarily stop at a bus stop, even if people are waiting at it. You will have to raise your hand to indicate to the bus driver to stop. Otherwise he might think that you are waiting for another bus and drive past you.
It is also worthwile to note that bus drivers give not change, and you should have the exact fare ready. Single fares range from 0.80 Euros if you are travelling as far as three stops and 1.70 Euros for over 23 stops, but you can also buy prepaid tickets at many news agents. There are also a variety of other tickets available. Check the Dublin Bus website for details.
Dublin has a fairly extensive bus network which is probably not the best by European standards but it gets you where you want to be.
Dublinbus runs a Nightlink service into the small hours of the morning to get you home after the pub kicked you out and you've depleted your taxi money on Guinness.
