On the weekend of September 18th and 19th, you can explore urban nature with your family with the many programs on offer through the “Long day of city nature.” If you go to their website you can see the entire program, and can filter your search for kids or youth appropriate events: There is so much to choose from and in locations all over the city! You can discover bees and insects, birds or beavers, go on a bike, boat, or canoe tour, go on a hike through fields, moors, or woods and discover medicinal herbs and edible plants and mushrooms. Make dyes from plants at the green market, and peek into the workday of a city nature ranger. https://www.langertagderstadtnatur.de/home
Check out the whole program here, and secure yourself a ticket and reservation in advance. You need to register all attendees and pay with Paypal or over the phone but I believe most events are under 6€. Some events have limited spots left.
