Natur-Park Schöneberger Südgelände

Tempelhofer Feld - Former airport turned massive public park. 386 hectares of open space - dogs can run off-leash everywhere except the paved runways (technically on-leash but rarely enforced). Best place in Berlin for ball throwing and fetch. Parking at multiple entrances (Neukölln, Tempelhof). U-Bahn: Platz der Luftbrücke (U6) or Boddinstraße (U8). No shade - bring sun protection in summer. Water fountains at entrances.
