Stretching for 350km from the vineyards of Würzburg to the foothills of the Alps at Füssen, the Romantic Road (RomantischeStrasse) is Germany’s most popular tourist route. You could spend a month exploring this string of perfectly preserved medieval walled towns, hilltop castles, mighty cathedrals and pretty churches. Stopping-off points include the enchanting Rothenburgob der Tauber, the dramatic castle Burg Harburg and the stately town of Augsburg.
