Rhine Falls - one of the most spectacular natural wonders situated on the border between the cantons of Schaffhausen and Zurich. This impressive waterfall is known as Europe's largest and most powerful waterfalls, with a width of 150m and a height of 23m. Aside from enjoying the sights you can also embark upon a boat tour to Rheinfallfelsen - a rock in the middle of the Rhine Falls - or take advantage of the viewing platforms that have been constructed on both sides of the river. For those wanting to find out more about this wonderful site, guided tours of various lengths start from Laufen Castle, located on the Zurich side of the falls.
