From Gasthof Tetter, follow the yellow summer signs into the valley along the Wilde Wasser theme trail. The accompanying path of the Untertalstraße is prepared for pedestrians by the grooming machine. After just a few meters you will reach the first highlight - the Tettermoor vantage point. Here you have a wonderful view over the wintry, snow-covered moor. Further into the valley, it goes past the lookout tower through the forest to the Waldhäuslalm (TIP: you can try Alpine Curling here).
Immediately after the Waldhäuslalm you turn right, cross the bridge over the Untertalbach and continue on the cleared forest path to the Sondl-Alm. Along the way you have a wonderful view of the cross-country ski trails, which also lead along the Untertalbach to the Sondl-Alm. From there we continue to the Sondl-Alm car park at the Sulzberg Bridge. You cross the bridge and now go right along the street for about 300 m until you finally reach the Weiße Wand inn.
You hike back to the starting point on the way you came or from the Sulzberg Bridge to the Waldhäuslalm, alternatively on the cleared road. From Waldhäuslalm you can then take the bus back out of the valley.
As an alternative to starting at the Gasthof Tetter, you can also start at one of the other restaurants, or even start from the Hinkerbrücke into the winter wonderland in the Untertal.
