Nestled in the heart of a wooded and preserved valley, the **Ruisseau de l'Étang Hervé** is a small, picturesque watercourse that calmly winds its way through the countryside before feeding the Gesvres. It is a true haven of freshness and biodiversity, particularly appreciated by hikers for the peaceful and intimate atmosphere it offers along its shaded trails. This wooden decking and footbridges that allow crossing the wetland and protected area of the **Marais du Ruisseau de l'Étang Hervé** were installed recently. The development work for this pedestrian path was awarded at the end of 2018 and the construction site was finalized and delivered between **late 2020 and early 2021** by the local company *Bois Loisirs Créations*. It is a superb structure that allows you to enjoy the coolness of the marsh without sinking into the mud and without damaging the ecosystem!

Very beautiful place. I was able to cycle around the lake but I'm pretty sure many of the paths are impassable in winter.

The west bridge of Lake Voireau offers a beautiful, unobstructed view of the reservoir. The largest body of water in Loire-Atlantique, this lake stretches through the heart of the forest. Its wooded banks and landscaped beaches make it a pleasant stopover for a nature break or a swim.

Some arcades are more accessible due to ongoing repair work. A diversion has been put in place.

The Provostière pond, with a surface area of 73 ha, is connected to the Vioreau lake by the Rigole des Ajaux. This complex is part of the supply system of the Nantes-Brest canal. Its hydraulic management is ensured by the Loire-Atlantique Department, which has owned it since 2008. A 5.5 km path on which a bird observatory is located allows you to go around the pond in about 1h30.
