Hessentag is Hesse's state festival, hosted by a different town each year. In 2027 it comes to Idstein, a half-timbered old town in the Taunus hills that last hosted it in 2002. Expect live music, food stalls, local clubs and, by tradition, a big costume parade.
For kids, the draw is "Der Natur auf der Spur", a family nature area in the Wörsbachaue meadows, run by the state environment ministry with HessenForst.
