To get to Saalbach Hinterglemm by car
cross from Germany at any number of points. Reit Im Winkl is a good one.
Normally one heads for head for Zell Am See, but before you get there
you will see a turn off before you get to that point. However if you are
coming from the other direction you will have to go through Zell am See
first. Salzburg and Munich are the best airports.
