The Palace Garden, Karlsruhe
The park behind the palace is a place for rest and relaxation for the whole city. In summertime you'll find a lot of people lying on the lawns or in the shadow of the large trees of this lush green oasis.
Walk around the park and find some of the sometimes hidden monuments and statues like the fountains on this picture.
Or let your kids ride a the little train that tours the garden during summer.
