Fairy tales come true in the Northern Lands. Here, trolls are regularly spotted in fabled fjords, leprechauns know where the gold lies, jewelers to the czars still create bejeweled Easter eggs, and mid-summer's sun never sets. From Copenhagen, sail North to Tallinn, Estonia, a perfectly preserved walled medieval town. Enjoy the next two days in St. Petersburg, viewing the Impressionist paintings at the Hermitage, and savoring the gilded baroque palaces of the Czars. In Helsinki, shop for traditional woolen sweaters, tableware and Scandinavian clothing. A day in Stockholm gives you time to stroll the cobbled lanes of Galma Stan, the old town, visit the Royal Palace or shop in this Swedish capital.
