The so called “Alte Salzstraße” is a path from the middle ages. It was an important trade route that connected the Lechtal, Bregenzerwald and the Kleine Walsertal. The name “Salzstraße”, which means salt-road, comes from the main good that was transported on this road, namely the salt from Hall in Tyrol. On this road the salt was transported into the Bregenzerwald. Until the late 19th century this walkway was the only connection between the Lechtal, the villages at the Tannberg and the Bregenzerwald. Only in the late 19. century the walkway was expanded to a driveway. Between Hochkrumbach and Warth this historic road is still preserved and is now used as hiking path. Through this preserved part of the old trade route you can reach Warth by foot in only 30 minutes.
