• Kids come without adults, and grown-ups have limited access to the grounds, so plan it as a drop-off rather than a visit together
• Staff help, not supervise: youth workers are there for play, crafts or emergencies, and kids can leave without signing out
• Long summer holiday closure: open only the first week of the summer holidays, and partly closed from Dec 24 to Jan 1

Robi Volta is a staffed adventure playground where kids come on their own, without a parent. Alongside an adventurous outdoor play yard, it has well-equipped workshops and indoor rooms for play and hanging out.

Youth workers help with games and crafts, listen, and step in for emergencies, but they don't supervise, and kids can leave whenever they like. With Robi Horburg, it was Switzerland's first Robi playground.
