On this route, you'll experience something unique in the world: Between Immendingen and Möhringen, the Danube simply disappears from the surface. On approximately 155 days a year – in spring and autumn – the river sinks completely, allowing you to hike through the riverbed dry-footed.

Highlight • Natural Monument

A large sinkhole; there are several more such sinkholes in the area. They are formed by the karst rock, which is partially undermined – this can lead to the caves collapsing and thus to these craters.

By train, change in Singen, to Immendingen. From there, through beautiful forests, a short stretch along the dry Danube and to the Höwenegg crater lake, then through forests again and back to the train station.

Gorgeous weather with temperatures between 24°C and 26°C.

A lovely, relaxed tour starting at Nina's Ess Art.
Past the Danube sinkhole, through the forest, up and down, and stopping in Hattingen for a delicious sausage salad and a sour shandy...
The highlight was the Höwenegg crater.
But surprisingly, there were few people there on Father's Day.
