Nearby Hohenschwangau castle, though not as splendid as its neighbour, is worth a visit, to see Ludwig’s boyhood home. It was built in the 12th century and then was renovated in Gothic style by Ludwig’s father Maximillian II in 1832.
Take the train to Füssen (2 hours, there’s a direct one daily at 08:51) and then bus N°9713 to Hohenschwangau. If you’re travelling by car, use part of the famous Romantic Road (www.romantischestrasse.de), which begins in Würzburg and culminates in Füssen. Parking below the castle costs €4. Buy tickets at the ticket centre in Hohenschwangau village, below the castle. From there, it’s a steep 30-minute walk up the mountain to the entrance. Alternatively, take a horse-drawn carriage (up €5, down €2.50) or the bus to the Marienbrücke bridge (€2.60 return), which is a ten-minute walk from the entrance.
