Hi Pat! Leaving Dingle, consider driving over the Connor Pass and stopping for beautiful views along the way. There is an option to take a ferry from Tarbert, avoiding a long drive through Limerick, but you may have more luck finding activities and lodging there (e.g. Bunmratty Castle, etc.). You will encounter the Cliffs of Moher as you approach Doolin, but consider timing your visit toward the very beginning or very end of the day to avoid big crowds - we stopped around 2 pm but I wish we had driven right by to our hotel and come back later. Tickets to the Cliffs allow unlimited and multiple entries for 24 hours, though you could hike there for free if time allows. Depending on weather you can take ferry trips to the Cliffs, and of course you can visit the Aran Islands for the day or overnight.
