The Romantic Road is intersected by the Castle Road (German: Burgstrasse).
The term "Romantic Road" was first used in around the 1950s in the American-occupied section of Germany. The name was initially known predominantly among American soldiers, who took their families on vacation there. The route is now popular with all nationalities. Signs can nowadays even be seen in Japanese.

The Europabus operates along the Romantischestrasse between April and October. Euro 58.50 is the adult fare one way from Würzburg to Füssen.
Those with more time on their hands can travel at a more leisurely pace by bicycle along the 420-km stretch of road in about ten days. Guided tours are also available to take some of the stress out of the journey—they will take care of your luggage and accommodation, and you can travel in their bus when it rains.
Most of the destinations along the Romantic Road can also be reached by train. 
The best-known places along the route are Rothenburg ob der Tauber, Baroque city of Würzburg (a major wine region), Füssen (at the foot of the Alps), Augsburg, and the small but delightful town of Dinkelsbühl.
