wide, dark canal with calm water on the left, bordered by a metal retaining wall. A paved path with a white line marking runs alongside the canal. On the right side of the path, there is dry, yellow grass and then a row of tall, green trees. Further to the right, a second, narrower paved path runs parallel to the first, with two people walking. A triangular road sign is visible in the dry grass. In the distance, a bridge crosses the canal, and beyond that, more trees and buildings are visible. The sky is partly cloudy with patches of blue. This scene is located along the Dortmund-Ems Canal in Lünen, Germany, specifically in the vicinity of the bridge that carries the Federal Motorway 2 (A2) over the canal. The path is part of the cycle path network that follows the canal.
