From the port in Thonon, you can regularly take the ferry to Lausanne. The crossing takes approx. 50 minutes. If you want to book a round trip in one day, the cheaper day ticket is already worthwhile. More information can be found at https://www.cgn.ch

In Thonon, there's the lower town, located at lake level with its beautiful harbor. The older upper town is well worth a visit if you're traveling by bike. The view of Lake Geneva is splendid.
