A section through the impressive natural scenery of the Rhone delta and Les Grangettes, a sanctuary for migratory birds that you don't expect to find on the heavily built-up lake shores. Through the villages of Le Bouveret and St-Gingolph, the small market town on the French-Swiss border, you reach the neighbouring country and follow the shore of the lake to the destination Thonon-les-Bains, the famous thermal health resort.
