No worries to get here
My Tip:
Coming from Germany

Under snowing conditions drive over the highway Munich to Wörgl - Kufstein , Kitzbühel and Zell am See

Under normal conditions i would advice you to drive of the highway
between Rosenheim and Salzburgat Siegsdorf and come in over
Bad Reichenhall to Lofer and than Zell am See .
