I'm planning on visiting Ireland in early April and we plan on renting a car and exploring for 4 days. We arrive in Dublin early in the morning on the first day and we fly out of Dublin on the 5th day in the afternoon. My traveling companion and me move pretty fast and jet lag isn't to much of a concern. I'm hoping to see as much as i can but am a little unsure on what actual travel time will be like. I would like to see Rock of Cashel, Blarney castle, Ring of Kerry, Cliffs of Moher, Ross castle, Glendalough and more. I would love to go see the Giants Causeway and Belfast as well. If anyone can give me some advice on the best way to do this it would be a great help ^_^.
