... you simply enter "Uferweg 228", "5752 Viehhofen", "Federal State of Salzburg", State of "Austria" into your GPS and follow the instructions of the friendly voice.
Arrive at the train station in Zell am See, Saalfelden or Maishofen, continue your journey by public bus to the “Förstereck” stop or you can check out a taxi, which will take you to Viehhofen very easily.
Arrive at Salzburg or Munich airport, onward travel to Saalbach Hinterglemm, ideally by a comfortable holiday shuttle – please make a RESERVATION beforehand! If you missed this, see "by train" or check out a rental car and follow the instructions under "by car"!
