Very beautiful riverside path. Thanks to the ban on bicycles, there are no cyclists either.

In September 2026, we tackled another section of it. We started from Birrwil down by the lake, walked to Delphin and back to Birrwil by ship. It was wonderful and the crossing by ship only cost CHF 2.50 per person with Halbtax. But then we had to retrieve our car, we had no choice and had to pay the ransom!!! My darling left a fitting comment. Dreamfully beautiful area, beautiful hiking trails; a sinfully expensive parking garage at the harbor in Birrwil (5 hours CHF 35.00)

It is a beautiful, but often strenuous, area. The route from the highlight "Baldeggersee" up to Römerswil is also recommended. A route for the more athletic or those like me, who support suboptimal athleticism with electric energy :-)
