My wife and I will be heading to Ireland during the first week of September for 14 days (13 nights). Right now we plan to land in Dublin and stay there overnight, then stay in Kilkenny for a night, drive to Killarney for 4 nights (1 day to visit Killarney National Park, 1 day for Dingle Peninsula and 1 day for ROK) then visit the Cliffs of Moher on the way to Galway for 3 nights (1 day for Inishmore and 2 days for Galway and surroundings), finally back to Dublin for the last night.
The help I need is planning the last 4 days of the trip before heading back to Dublin for a night. The Rick Steves book says we can make it up to Donegal and Derry on a 14 day itinerary. I’d love to see that area but question whether that would be too much. I am also considering staying 4 days in the Connemara National Park area but I was wondering if that part of Ireland is much different than the Killarney area and if that is too long to stay there. I was also wondering if an overnight on an Aran Island would be worth it. Any thoughts or suggestions would be greatly appreciated. We will have a rental car.
