Tickets can be purchased either online or at the Ticket Center in Hohenschwangau. The tickets must therefore be purchased before going up to the castle. Neuschwanstein is always worth a visit ...
From there, hop on the No. 78 or No. 73 bus (which departs directly from outside the train station) to the Hohenschwangau Neuschwanstein Castles, Schwangau stop (about a 10-minute ride).
