A pretty iron bridge, built for farmers at the time. Here the path along the water was in a bad state in April 2026 (a warning was installed on one side of the section, but a detour through the forest is possible).

Beautifully done street sculpture. Why not position one of your friends in the peloton and grab a photo of them riding with Anquetil et al?

A stretch on the dam before the Trehu Moron dam. The landscape is constantly changing. The canal meanders through the countryside here. I love this landscape, and it's a good mood to drive here.
