Limerick is a great place to visit, and an excellent base of operations if you want to explore the beautiful West coast of Ireland, plus the hinterland of Limerick, Claire, and Tipperary counties.
But it's not as easy to get here as it should be.
It used to be that there were many flights into Shannon Airport, which is the closest and most logical choice. Unfortunately that once prestigious transportation hub is only just coming out of a long period of decline and mismanagement. It currently has far fewer flights than Dublin.
Both airports suffer from what is a terrible Irish problem, the poor rail service. In fact, there is not a single Irish airport connected to the rail system! Worse yet, if you choose Cork, Knock, or some other point of entry, you won't even get good coach service, and will be practically forced to rent a car. In my role as festival organiser I've often advised people against Cork, which, though significantly closer to Limerick than Dublin, requires a change of buses in Cork City, making travel next to impossible at morning or evening hours -- when flights are actually likely to arrive.
So that leaves Dublin as the next best choice, in the event that you can't get a good connection to Shannon. You'd think it would be a piece of cake to get from Dublin Airport to Limerick. There are indeed several options, but read on and I'll fill you in on the best choice.
