I see a sign with German text ("Lebensgefahr") near a canal and a large industrial brick building with tall chimneys. The vegetation and the style of the building strongly suggest Central Europe, likely Germany. The bright, clear weather and lush trees indicate a temperate climate. I suspect this is near an industrial site or power plant in a German city. I am fairly confident this is in Germany.

then: forward

The path is a gravel trail through a wooded area next to a canal. The industrial building in the background remains a key landmark, suggesting a location near a waterway in a German city. The presence of cyclists confirms this is a recreational path. Given the industrial architecture and the canal, this looks very much like the industrial districts of Berlin or a similar German city. I am fairly confident in this assessment.
