Chavannes-sous-Orsonnens is a commune in the canton of Vaud in Switzerland.

From the hill of Romont, the path descends into the valley of the Broye River. It is a moderate distance stage with a smoother profile than the previous one. The route passes through a landscape of cultivated fields and small villages. Arrival in Moudon, an historic city with an enchanting old town, is a pleasant final stage.
