Vertonne (rivière) walks

The Olonne forest stretches across the dune massif that borders the ocean between Brem-sur-Mer and Les Sables d'Olonne. This massif completely isolates the marshes located between the forest and the first hills where the vineyards of the Vendée fiefdoms flourish. This circuit offers a walk between the ocean and the banks of the Vertonne through the flat, open landscapes of the marshes, the more rugged forest and the immensity of the sea.

Set off to explore the Marais des Olonnes.

A very pleasant walk in the Île d'Olonne Marshes Nature Reserve. You are likely to see herons and other species.

Circular to the east of the village of Grosbreuil with typical Vendée bocage landscapes. Calm and relaxing, it allows you to discover a diverse flora, a beautiful sunken path and the trail called "Sentier des Gaulois" (Gaulish Trail).
