“When a man is tired of Dublin, he is tired of life!” My Guess is that you'll all make haste to the Guinness storehouse. I can't argue with that decision but Dublin has so much to offer in art, history, distilleries and of course, great pubs.

Newgrange is a fully excavated 5,200 year old passage tomb located in the Boyne Valley. On the shortest day of the year, the light hits the back of the tomb. Worth a stop on the way back to Dublin if you have the time.
