The path is paved with red bricks and light stone, typical of Northern European urban park design. The presence of a "no stopping" sign with a red circle and blue background is common in Germany. The architecture across the water and the mature deciduous trees suggest a temperate climate. It feels like a lakeside promenade in a major German city, possibly Hamburg. I am fairly sure of this location.

The view of the Alster lake in Hamburg is unmistakable, particularly the promenade along the Außenalster. The distinctive paving pattern and the specific layout of the shoreline confirm this is a popular recreational area in the city. The architecture visible across the water matches the upscale residential buildings found in the Harvestehude or Rotherbaum districts. I am very confident this is Hamburg, Germany.
