From Zurich:
Motorway exit (no. 80) St. Gallen-Winkeln, then head in the direction of the city of St. Gallen over the ‘Fürstenlandbrücke’ bridge. Approximately 300 m after the bridge, keep right, then after around 200 m, before the Tamoil petrol station (industrial signposts), head right (Straubenzellstrasse) up to the train line, then take another right. You’ll see the signs for DIXA AG after around 150 m. You made it!
