Here, the mineral character seems predominant in the landscape: cliffs, boulders and old quarries blend very well with the waterlogged soils and the luxuriant aspect of the alluvial forests.
This duality of the landscape gives a very special atmosphere, perfectly expressing the interest of man for this place.
This was expressed in particular by the construction of industrial works (mills) and the use of stone, as evidenced by the many existing quarries.
From the heat of the south-facing hillsides, you will suddenly find yourself refreshed by an icy breeze coming from the entrance to an old quarry.
Distance of the course approximately 4,4 km.
