Södermalms Stadsdelning has put together a calendar of events for kids between the ages of 6-17 (avg age of activities is 8-12 years) between week 24 and week 28.
This initiative is a brilliant step for slightly older children, not quite ready to start the summer on their own whilst some parents are still at work, but who are also looking for barrier free activities to get their teeth into.
The whole programme is available on the Stockholm Stad website via this link.
