You can fly to Cork Airport or to Kerry Airport, depending on where you fly from and the airline. From both airports it is about 2 or 2,5 hours driving. The routes are so beautiful, you are on a holiday immediately.
By car you arrive either in Rosslare in the south-east of Ireland or near Dublin, Holyhead, depending on which route you choose to drive. From Rosslare and Dublin it is about 5 hours driving. Lovely routes too!
