• Kids only on weekdays: Wednesday to Friday afternoons are for children on their own, without a parent or carer
• Family Saturdays welcome kids of every age with parents, grandparents and relatives, and in good weather there is cooking over the fire from 12pm to 2pm
• No supervision duty: staff help when asked, but kids can leave without signing out, so agree a pick-up plan

Robi Bachgraben is a staffed adventure playground run by the Robi-Spiel-Aktionen association. Besides a rambling outdoor play area, it has well-equipped workshops and indoor play rooms.

Kids decide what they do and how long they stay. The youth workers help with play, crafts or a listening ear but are not there to supervise, and kids can leave without signing out.
