Transfer from Schaffhausen to Kreuzlingen
To make this a day on the water you would take a rhine boat from Schaffhausen to Stein am Rhein and from there on a lake steamer to Konstanz / Kreuzlingen! (you could also take the train but that would much less exciting!).
Take the boat at 9:10 AM in Schaffhausen to arrive at 11:15 AM in Stein am Rhein. You could continue on the same boat and would arrive in Kreuzlingen at 1:55 PM, or you can interrupt and discover Stein am Rhein which has an equally beautiful Old Town and a few good fish restaurants.
If you do interrupt in Stein am Rhein you have boats to Kreuzlingen at 1:15 and 3:23 PM, both taking around 2 hours 45 minutes to arrive.
> If you are planning to explore Stein am Rhein then it may be a good idea to use Fast Baggage today, to ship your luggage from Schaffhausen train station to Kreuzlingen train station. See the paragraph in the beginning for more info.
