Departure from Olonne-sur-Mer (Vendée)
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.
