Are thinking of stopping in the Chiemsee area for an overnight on the way to Salzburg (late September). Has anyone driven from Chiemsee to Salzburg? (We will already have a rental car). How does the border crossing compare train vs. car? I am trying to decide if it will be more enjoyable and less stressful to book several days in the Chiemsee area and travel to and from Salzburg. Another option is to travel via car and make Salzburg the next overnight stop. Any input is appreciated. Thanks!
