FATMAP difficulty grade
Leave Sargans, heading west from the train station, following the tracks until you hit the rail and motorway underpass where you need to turn left into the village Mels.
Cross the Seez bridge and follow the road up to the small Nidberg Castle.
Follow the road past the castle, turning left at the start of the forest and come onto the Vermolerweg trail up to the village of Hintervermol.
Continue along the path through alpine meadows and woodland until you hit another village, Mülli, where the trail once again joins the road into the Weisstannental valley.
After a short while, turn right onto an uphill climb, coming to the high-alpine trail that takes you all the way to Weisstannen. **Sources** http://www.via-alpina.org/en/stage/109
