Here is a list of outdoor places in Munich and the surroundings where you can play and have fun with your kids. They are excellent for sending time outside on a fresh air and your children will really enjoy the time spent there.
Beerencafe
There are several Beerencafe in Munich that are definitely worse visiting with children.
They offer the possibility to pick fruits and vegetables yourself and also have playground and restaurant area where you can relax and grab some good food while children are playing around.
Animal parks
Zoo München (Tierpark Hellabrunn)
The zoo in Munich is an excellent place to spend some time with the children.
If you are planning to go there more than twice a year, we will recommend you to buy the annual ticket because the price you will pay is almost equal to 3 daily tickets.
Another recommendation is to go there by bike or public transport. The parking space around the zoo is limited and in sunny days, especially during the weekends, there is a long queue of cars waiting to enter the parking space.
Wildpark Poing
This is an excellent place to spend the whole day with the children. You can see a lot of animals and there is big playground and a picnic area:
We will recommend you to take with you a picnic blanket and bring your own food for lunch, especially if you are visiting it during the weekend. There is also a restaurant, but during the weekends, the queue may be quite long.
Cirkus Krone farm
Home of Circus Krone’s retired animals, it is an excellent place for entertainment.
There are several areas where children can have fun, a museum, Krone farm tour and much more. We can definitely recommend you to visit it.
Amusement parks
Märchenwald
Märchenwald amusement park in Wolfratshausen is an excellent place to entertain small children:

Playgrounds
There are plenty of playgrounds in Munich so here we will list only few of them that we found a bit more interesting.

Besucherpark at Munich airport
This an interesting playground near the airport.

You can park at one of the airport parking areas which is exactly next to the playground. You can watch the airplanes while taking off and landing and the children can play on the playground.
Since there is not much shadow there, we would recommend visiting this playground during cloudy or not so hot days.
If you want to explore more playgrounds around you, just do a search in google maps, or have a look on some of the websites like https://spielplatzliebe.de/ and https://www.spielplatztreff.de/ which are focused on playgrounds.
There is even a playground app available at https://spielplatz-muenchen.de that allows you to find playgrounds around you and filter them by selected criteria.
Lakes
There are several lakes around Munich where you can easily spend couple of hours and even a whole day. You can make a picnic and play outdoors. At some of the lakes grilling is allowed at designated areas.
Schwabinger Bach in the English garden is a nice place for a picnic that is very easy to reach.
Olympiasee in Olympiapark is a nice place for a walk.
Feringasee near Unterfohring is very close to Munich. It can be reached by bike and also offers plenty of parking spaces. There is also a big area for grilling.

Other ideas
Recycling center (Wertstoffhof)
You may consider visiting some of the recycling centers (wertstoffhof) in Munich to show the children where items for recycling are collected. This is not a place where you can spend a lot of time (usually around 30 minutes are enough), but it may be interesting for the children to see it.

If your kids like horses, they will definitely like this show.
