We have three nights booked near Berchtesgaden this summer. That leaves us part an afternoon and two full days to explore the area. One day and probably what's left of the first afternoon will be spent around Berchtesgaden and Koenigsee. For the second day, I am trying to decide between Herrenchiemsee and Hallstatt. Our earlier travels take us to Salzburg and Vienna, and after this we will go to Munich. I may be able to see both on this trip, but if I don't want to be too rushed just to check things off a list. If you had to make the choice, which would you see and which would you drop?
