It’s a long way until next St. Patrick’s Day, but if you still have some partying left in you after the holiday, get yourself to the Emerald Isle for an authentic Irish cultural experience. With so many regions worth checking out, Ireland is best explored by car, either driving yourself or, better yet, with a driver-guide. Fly into Dublin in the east or Shannon in the west -- preclearing U.S. customs at either airport on the way home -- and circumnavigate the island for an enchanting journey through the land of St. Patrick.
