Erfurt english englische kids

Going to be in Germany for 10 days with my 8 year old who mostly just speaks english and was wondering if any english speaking families are around for a few playdates or advise on groups and activities.
Or playdates with kids who are learning english so my son can pick up some german would also be fantastic.


I’m not sure if it’s still relevant or not but I’m case it is: there are many English speaking families who come to the playground in the park called „Nordpark“- the playground itself is great as well!
