Eins-und-Alles Welzheim, Sensory experience park in Welzheim, Germany.

Eins-und-Alles Welzheim is a sensory experience park where visitors explore and train their senses through multiple stations. Both indoor and outdoor areas offer activities focused on smell, hearing, touch, and balance.

The park opened on 6 July 2007, after a first construction phase in 2006 and early 2007, financed by a roughly 2 million euro loan from GLS Gemeinschaftsbank. It grew out of the Christopherus Lebens- und Arbeitsgemeinschaft at Laufenmühle, which wanted to bring visitors into the isolated Wieslauftal site rather than move residents out. The concept follows Hugo Kükelhaus's sensory field and Rudolf Steiner's theory of the senses.

The facility serves as a workshop for people with disabilities under the management of Christopherus Lebens- und Arbeitsgemeinschaft, promoting social integration.

The park is located at Laufenmühle 8 and is easily accessible by car or public transport. Dry weather works best for a visit, as many areas are outdoors.

The 4.5 km Wunderweg loop above the Wieslauf holds a 250-metre labyrinth, a barefoot path and the Beuys-Platz, where Joseph Beuys's poem "Lebe" is set on mirrors. The Waldkugelbahn makes a rolling ball audible as well as visible. A willow cathedral, the Zukunftsbau, was built from 2010 with the Albertville-Realschule.
