By Car:
Out of the main cities Ireland’s roads remain relatively congestion free, making driving a good option. The national speed limit is 55mph/88kph, except where posted otherwise.
By Bus:
Bus Éireann operates throughout Ireland and its services are reliable, if infrequent. It's possible to travel by bus between all major towns, but routings can be complex, involving several connections, and hence very slow. Buses are generally twenty to fifty percent cheaper than trains, with the best value given by private local companies which operate in most Irish counties.
By Rail:
Irish Rail operate trains to the main cities and towns; on direct lines it's by far the fastest way of covering long distances, but the network is by no means comprehensive - Donegal, for instance, has no service at all. Generally, train lines fan out from Dublin.
By Ferry:
Ireland is served by numerous services to and from Great Britain and France. Daily services run between Ireland, Swansea, Holyhead, Pembroke, Fishguard, Liverpool, and Roscoff and Cherbourg in France.
By Air:
The Republic of Ireland is served by two large international airports - Dublin and Shannon.
Services from London are frequent and moderately priced. There is also wide range of options from main cities in the UK, with ever-increasing number of airlines connecting regional UK airports with Ireland.
