On the southern outskirts of Hallstatt, the Echerntal opens up, which extends in a east-westerly direction at the foot of the Dachstein massif. The Waldbach rises at the foot of the Dachstein massif and comes through the Waldbachstrub, a steep, narrow rocky gorge into the Echerntal, flows through the Echerntal and into Hallstatt Lake in Hallstatt Lahn.
