While waiting out a storm here they visit the Guinness Storehouse and learn about Ireland's most famous beer. Next stop is Carlingford on the border with Northern Ireland, known as the best place to search for Leprechauns. In Northern Ireland they stop in Belfast and discover new things about the ship Titanic which was built here.
