The Romantic Road consists of 360km of country road that runs the length of the Bavaria, from Wurzburg, in the North, to Fussen, in the South, almost to the German-Austrian borderline.
The Romantic Road has almost 1,000 years of history. A trade route during the Middle Ages, it still retains much of its medieval character. The road often winds through forgotten sections of countryside, connecting walled towns and picturesque villages. Travelers may enter a town through arched gateways like in the case of Rothenburg od Tauber. Inside, you will find gothic cathedrals and half-timbered houses overflown with hanging flower baskets or baroque and Renaissance buildings. Fairytale castles, fountains, gardens, outdoor cafes, authentic restaurants and historic hotels fulls of characters are never far.
You can "do" the Romantic Road in a day by taking the bus that goes the length of it. The bus leaves from Frankfurt Hauptbahnhoft at 8:00am and arrives at Fussen at 8:00pm. Along the way, it makes several stops in towns like Wurzburg, Rothenburg, Dinkelsbuehl, Augsburg, etc..
But these enchanting towns really deserve more than a 1 or 2hrs stop and a rental car is your best bet. Spend enough time in Wurzburg to see the Residenz, which is part of the UNESCO World Heritage, and the Marienberg Fortress. Stay at least one night in Rothenburg, the best preserved medieval town in Germany. Or, if you do not like places that are swamped with tourists, stop in Dinskenbuhl, a historical old town with gateways, towers, walls, and moats. And of course, do not miss Neuschwanstein, King Ludwig II's fairytale castle located in Fussen.
