If you do spend time in Dublin, in addition to the Guinness Storehouse, there's also the Jameson distillery to tour if that's more your style. If you're a history buff and into true crime, definitely take a tour of Kilmainham Gaol, a former prison that's now a museum. And make sure to take a walk through Trinity College, which houses the Book of Kells. Oh, and for traditional Irish music and delicious pints, head to The Brazen Head, Ireland's oldest pub. For grub, head to Johnnie Fox's, Ireland highest pub! While all of this might sound like a lot, you can easily do most of it in a day.
