Have you been to see all the interesting sites in Munich already? Well if you have and still want to see more why not hop on a train to Salzburg. The deutschacademie is very close to the Hauptbahnhof anyway and this makes it very ideal to take an afternoon after classes to visit this wonderful city. You will get the opportunity to  see the Festung & Schlösser, the beautiful Mirabell gardens, the Mozart Geburtshaus (you will learn about him during you deutsch course) Salzburg is closely associated Mozart and his world famous compositions.Thats not all you can do and see  lots more. If you are interested you could even get to do the Sound of Music Tour.
