Neuschwanstein is build 30 min walk away from his childhood house the Hohenschwangau Castle.
Ludwig II had 2 big passions: Luis XIV of France and Richard Wagner so everything he built was with them in mind.
Stay overnight in Füssen, which is the city nearby. We stayed at Bavaria City Hostel (lovely place, totally recommended). From there we left early morning walking towards Hohenschwangau & Neuschwanstein. You can rent a bicycle or go by car. We decided not to enter any of the 2 to have more time for Linderhof. You should know that you can only buy the tickets at the ticket office close to the Castle and there are certain hours when you can enter.
There is a reduced price if you buy entrance tickets as a bundle for the 3 Castles.
The Best view of the Castle is either from Maria Brücke (unfortunately closed when I was there for refurbishment) or from up in the mountains, but you should be an excellent climber for that :)
As I have mentioned before, besides Wagner, Ludwig II has as second passion the Sun King of France, thus he decided to create a small replica of Versailles in Linderholf. Ludwig II finished this castle and enjoyed spending a lot of time here. As a symbol that he was at at home 2 Peacocks statues were brought outside in front of the castle
The candles from the glass chandeliers in the bedroom have been never lighted. The room looks over fountains that create a sort of a old style aircon in summer days.
The mirror room highlight is the blue lapis-lazuli amethyst brought from Afghanistan out of which the fireplace is built and the fact that the 2 mirrors are placed in front of each other creating the impression of never ending line of mirrors if you stay right in between them. The most expensive piece in the castle is an ivory candelabra.
Ludwig II wanted to eat alone and nobody was allowed to enter the dinning room during his dinner (not even the servants) for this a magic table has been put together which could be lowered down and lifted up on ropes.
Ludwig was for sure a completely lunatic but still he left so many great things to see and discover. Still today investigations are being done about his death and a lot of uncertainty about the way he died.
