Dublin Bus

A single bus station, Busáras, is the terminus for Bus Eireann services to almost all towns and cities in Ireland (except for a few services to County Meath and County Dublin, which leave from the surrounding streets). It's next to Connolly train station, 10min by foot from O'Connell Street. There are also services to Northern Ireland and Eurolines services to Continental Europe. Luggage lockers are in the basement, along with the pay-to-enter public toilets.

Luas

The Luas tram runs frequently and reliably, and is handy for getting around the city center. There are two lines - red (running from Connolly railway station and the Point Theatre to the suburb of Tallaght) and green (running from St. Stephen's Green to Bride's Glen in Cherrywood), a third line; the Luas Cross City is under construction. The current lines do not connect. The distance between Abbey Street on the red line and St Stephen's Green, the start of the green line, is about a 15 min walk. Construction work, which will extend the green line, connecting and extend the two lines began in June 2013 and is currently in its final stages with completion expected in early 2017. Tickets can be bought on the platforms at the machines and do not need to be validated. The fare structure is based on zones, with rides within the central zone costing €1.50. A large amount of further expansion of this network is expected within the next decade.

Running time: 05.30-00.30am from Monday to Friday, 06.30-00.30am in Saturday, 07.00-23.30pm in Sunday

Aircoach is one of the important bus companies in Ireland, providing 24-hour transport services between airport and city center. Dublin Bus Company is another main force of Dublin Public Transportation and features many bus routes and airport service. The running time is from 6:00 a.m. to 11:30 p.m.

It should be noted that, while there is effectively no queuing system at bus stops, those paying with cash generally enter to the left of the doors, and those using card tickets enter to the right. Your position in a perceived queue for a bus may be effectively irrelevant once it arrives.

Sightseeing buses are both convenient and cheap for tourists, tickets are sold by drivers and generally cost 10 euro, which is valid for 24 hours. Several Dublin based tour operators offer daily tours from Dublin city to the most scenic, historic and popular attractions in Ireland.
