This NAJU group — the children's and youth branch of NABU, the German nature conservation association — invites children to discover and explore nature in Kreuzberg hands-on. Activities include finding out who gnaws round holes into hazelnuts, where ladybirds hide in winter, and how to make soap from soapwort, all while learning to protect the local environment. The group, led by Meike Lechler and Ellen Mey, meets every two weeks; registration is required.
