Salzburg for most Germans I would say, is a nice Austrian city conveniently located right across the border so perfect for a good day trip. Before going there I was actually not aware that it was such a famous location for The Sound of Music, too (I was thinking more…Mozart). However, you can visit many of the movie locations fairly easy so I would definitely recommend to watch the movie and then go on a nice movie location hunt once you are there. The locations are absolutely stunning, too, so definitely worth a visit!
