inside the Charlottenburg Palace
The green areas of the park are free, so you can go there to have a walk even if you are not interested in the palace. It covers a large area and you can get in from the entrance just near the "New Pavillon" (Neuer Pavillon a.k.a. Schinkelpavillon) placed on the right of Luisenplatz.
