2. The Green Valley
The Vallée Verte des Jaulnières was developed in the 1980s in such a way as to respect and reinforce the natural landscapes. It is essentially made up of native plants: the flower beds are absent, the paths not bordered. maintenance is limited to the necessary imposed by attendance. This more natural management of the valley where mowing replaces mowing on the less frequented sectors allows over the years the reintroduction of a certain diversity of fauna and flora.

Two concrete weirs were removed in 2021 to allow the Yon to regain its natural flow.
