We will have 2 free days during our trip to Dublin, and would like to travel to other areas, either with car rental or bus or train. We can take day trips during those 2 days, or do an overnight trip. We are open to all suggestions, such as Galway overnight ? or day or overnight trip to Killkenny/Rock of Cashel/ Cobh ? We love to pack in as much as we can. We want to see rural areas, villages, picturesque Ireland. Please give us some advice. Thanks !
