If you are planning a trip to Ireland the first thing you need to find out is what airport you ar flying into. Dublin and Shannon are the main international airports in the Republic of Ireland. If you are planning on visiting Dublin city then are best landing in Dublin. If you land in Dublin and you want to go West then you have to travel accross the whole country to get to the West of Ireland.
You can either hire a car or use public transport (bus/train) to get to the West of Ireland. Galway would be the major destination before heading to Rossaveal. Galway takes 2.5 hours by bus or train from Dublin. If you want to avoid the cities and just go to the West of Ireland where all the beauty spots are and where the most traditional culture is then you will need to land in Shannon airport. Shannon is one hour from Galway. Galway is one hour from Rossaveal which is the main ferry port for boats to the Aran Islands. If you are coming from England then you can take a boat to Belfast and head to Dublin before heading to Galway.
