From Hinkerbrücke car park take the theme trail "Wild Waters" to the right of the bridge. After a couple of meters the first highlight awaits you: nature conservancy Toteisboden: this moor is a geological anomaly in Untertal valley. Along the wide trail you then continue to Tetter moor, where you cross Untertalbach creek over a wooden bridge while enjoying the great view to the moor. You walk up to Gasthof Tetter Inn and then continue right on the hiking trail that runs next to Untertalstraße road. Soon, you reach Waldhäuslalm Inn, and just 50 m beyond the inn you turn-off right and follow the trail along the creek again. You continue your hike towards the valley head - at first through a forest, then over the meadows around Sondlalm Inn. At the trail junction 400 m after Sondlalm you make a right (you could also walk along the road for about 5 minutes to reach Gasthaus Weiße Wand Inn) and continue along the theme trail Wild Waters until you reach Seeleiten car park and Almgasthaus Riesachfall Inn. Take the same way back or use the Planai buses.
