The Rhine Falls is a waterfall located in Switzerland and the most powerful waterfall in Europe. The falls are located on the High Rhine on the border between the cantons of Schaffhausen (SH) and Zürich (ZH), between the municipalities of Neuhausen am Rheinfall (SH) and Laufen-Uhwiesen/Dachsen (ZH), next to the town of Schaffhausen in northern Switzerland.

The High Rhine is the name used for the part of the Rhine that flows westbound from Lake Constance to Basel. The High Rhine begins at the outflow of the Rhine from the Untersee in Stein am Rhein and turns into the Upper Rhine in Basel. In contrast to the Alpine Rhine and Upper Rhine, the High Rhine flows mostly to the west.
