One of the most visited scenery in Switzerland is Rhein Falls. It is the largest plain waterfall in Europe. The falls is located on the High Rhine between the municipalities of Neuhausen am Rheinfall and Laufen-Uhwiesen, near the town of Schaffhausen.
If you are looking for a place to let the time pass that does requires any money at all, this is the right place for you. You can just pack a picnic lunch and look at the view of Europe’s largest waterfall. Nearby, you will also find a medieval castle which also houses a hostel for affordable and interesting accommodations.
