Stuttgart Spring Festival (in German called Stuttgarter Frühlingsfest or sometimes vernacular Cannstatter Wasen or just Wasen) is an annual fair that takes place in the German city of Stuttgart between the middle of April and the beginning of May. The festival takes place on the Cannstatter Wasen, traditional fairgrounds in Stuttgart's Bad Cannstatt district. It is slightly smaller than the festival in the autumn (and therefore occasionally also called the "small Wasen"), but it is the largest spring festival in Europe. Like the autumn fair, the Frühlingsfest offers a variety of fairground attractions. The tallest attraction is the 47 metre Ferris wheel and the fair almost invariably features a major roller coaster.
