Starting out from the Baroque-era esplanade in Solothurn, the route follows the River Aaare to Zuchwil, where the hybrid power station uses water and electricity to produce hydrogen. Numerous features have been installed for the Wasseramt route: a bridge over the Emmen canal at Derendingen, the «Rolf Sauser Platz» in Subingen, and the bridge over the River Ösch. Immediately thereafter, you will see a beautiful nature conservation area. The route follows the Niedermattbach brook to Hüniken, past gigantic manure heaps. After Etziken, the route reaches its highest point: here the water tower, built in 1931, looms above the forest. It is worth taking a look back over the open fields to Solothurn and the Jura range behind it.

Past the Bahn2000 tunnel mouth – which trains rush into and out of at regular intervals – the route descends via Aeschi to the Burgäschisee lake. This is situated in a basin carved out by glaciers. The water-level was lowered in 1943 to reclaim land. Stilt-house settlements were discovered in four locations and, due to special finds made here, declared a UNESCO World Heritage Site. An illustrated information board shows what life might have been like for the stilt-house dwellers. Today, the lake is popular among bathers at the lido or the bathing area.

Continuing northwards, the route still crosses the lake’s outflow rivulet and the River Önz, past the pleasing sight of tastefully restored farmhouses and into Herzogenbuchsee, where it ends at the train station.
