The nature museum of Solothurn is not so big, but it has its charm. A great place for the whole family. Children can touch many things like a bear fur. Lots of very interesting things to learn for the small once as well as the parents. It is free of charge and not so far form the train station, just a cross from the river Aare. Solothurn is any way worth a visit as the nicest barock city of Switzerland.
