September 15, 2025,Wetter (Ruhr) 🌬 um den Harkortsee gepustet

It's autumnal! 🌿🍂🍃 Dark clouds - sunshine - jacket on - jacket off 😂 And then it turned out to be much warmer and sunnier than forecast, but with a lot of wind. Nevertheless, the ride was still fun. 👍😉

At the beginning of the Harkortsee is the Ruhr Viaduct 🌁 from 1878. This railway bridge 🚂 spans the Ruhr …

Even though I've walked countless times, I've discovered so many beautiful motifs... I stopped into the café at Wertreiben Castle. Unfortunately, the …

December 10, 2023,Blick auf Viadukt – Die Ruhr Runde von Wetter (Ruhr)

After all the altitude on the last few tours, I was happy to be out in the flatlands today. I was finally able to get up to speed a bit again. The tour is easy and even offers opportunities to stop off, at least in the summer 😅. You can reach the starting point by bus, or you can walk …

November 15, 2022,Im Dunklen um den Harkortsee

Today, together with Kris, we went for a walk around the Harkortsee at 13° C and falling darkness. Flashing and reflective like a highway construction site.
But this time the video camera stayed at home.

June 5, 2026,Rundwanderung um den Harkortsee

Today's tour started with my four-legged friend at about 14 °C, about half an hour after sunrise, at the parking lot of Wasserschloss Werdringen.

From there, we headed along the fields towards the Ruhr bridge in Wetter. After crossing the bridge, the path continued through Wetter and then along the Harkortsee towards Herdecke.
