Here the origin of the path can be seen: it was an old railway. The old station is well maintained.

The reconstruction is great! But we left some parts in ruins, which preserves the character of an old building.

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.
