I would like to visit Constance (Germany) with my van, and also see the other side of the lake. Is there a way to cross by ferry or would I need to drive along the lake?
It is possible to cross by ferry as mentioned by this website:
The car ferry Meersburg - Constance that can also be used by pedestrians or cyclists, makes trip planning even more flexible. There is another car ferry shuttle service between Friedrichshafen and Romanshorn.
