One of the most impressive natural wonder in Central Europe are the Rhine Falls. They are 150m wide and 23m high. The average water flow changes over the year. In Winter its going down to around 250m3/s and in Summer it averages at 700m3/s – and the more water runs the more impressive the Rhine Falls get. This year should become a pretty good year – there are loads of snow in the Mountains and when this snow starts melting in Spring and early Summer, the Rhine will receive a lot of water.
Visiting the Rhine Falls is always fun – but its best in summer when its hot and the water filled air refreshes you. There are a lot of boat tours – you can just cross the Rhine beneath the falls (going from the one Swiss province (Zurich) to another (Schaffhausen), you can take a ride towards the falls (these boats get pretty close) and there is on trip that takes you to a rock inside the falls, which can be climbed up (via stairs) and will provide you with the best views of the spectacle.
On both sides of the rivers are Castles – Schloss Wörth on the Schaffhausen side (featuring a restaurant) and Schloss Laufen on the Zurich side (with a museum about the falls in it).
The Rhine Falls were one of the first places in Europe that were visited regularly by Tourists. In my opinion it is still an absolute highlight and no one should miss out on that.
Visiting the Rhine Falls will take about half a day – afterwards you could visit the picturesque town of Stein am Rhein – more on that later!
