On the Goulaine, a break before the ascent or after the descent of the Butte de la Roche for a 360° view. The place is prettier with sunshine. With Nantes cow breeding nearby 👍

The Pont de l'Ouen separates the Goulaine marsh into two bodies of water: the upstream pond, baptized “Claude Dupas” whose level it controls, and the downstream pond, baptized “Adrien Menereau”.

Small pond located in the town of Coursay. Numerous picnic tables by the water or under the trees. For gravel enthusiasts, the vineyard path which starts from the pond and goes to the hamlet of Loges, in Monnières, is really very nice.

At the end of a long straight line on which you can test your speed is one of the most beautiful spots to admire the Goulaine marsh.

The Ouen Bridge spans the Goulaine river and separates the upstream basin "Claude Dupas" from the downstream basin "Adrien Menereau". Picnic tables nearby. Nice place for a break. No water fountain seen on the other hand.
