The Via Francigena by bike in Switzerland follows as far as possible the pedestrian route, but above all the official cycling routes of Switzerland mobile. It first crosses the border and the Pre-Alps to reach the Swiss plateau and finally the capital of the canton of Vaud, Lausanne.
It follows the shores of Lake Geneva (Lac Léman) and then follows the Rhone bank to Martigny.
The ascent begins in this town. The last part from Bourg-Saint-Bernard to the Great St. Bernard Pass is the most difficult but perhaps the most beautiful before descending into Italy towards Aosta...and Rome!
