Mills, imposing factories, converted industrial buildings, workers' housing estates and industrialists' villas: this circular route follows the trail of Winterthur's industrial past, with information boards that document its diverse industrial heritage sites. Starting by the main railway station, it first runs past the old locomotive depot to the former Haldengut brewery. Beer was last brewed here at the foot of the Lindberg in 2002; the site's historic walls now surround modern apartments and commercial spaces.

On the outskirts of the city stand the Hegi mill and the «Reismüli», Winterthur's last sawmill powered by a water wheel. Cyclists pass the Sulzer area of Oberwinterthur to reach the Swiss nail factory, the only one left in the whole country. It produces more than 200 types of nail and has a set of machinery from 1895, which can be visited on the first Monday of each month at 11 a.m. At the next stop, cyclists can discover the boiler house of the former silk spinning mill and the converted industrial building in the nearby Schleife area. The route continues past an industrialist's villa, the first Rieter spinning mill and the former Aspasia factory, where soap and toiletries were manufactured until 1975.

On the way towards Töss, the route passes workers' housing estates as well as the Rieter industrial area. These are followed in Wülflingen by the protected Wespi mill, the once proud Beugger spinning mill and Switzerland's first water-powered factory, the spinning mill Hard. From here, the path follows the Eulach river back to the main railway station.
