Arena-Sportpark, Sports complex in Stockum, Germany

Arena-Sportpark is Düsseldorf's largest sports complex, covering 95,000 m² in Stockum north of the Messe and the Merkur Spiel-Arena. Its core is the Kleine Kampfbahn, a grass pitch with a 400-metre synthetic track, floodlights and a covered stand of 195 seats and 1,350 standing places, alongside an indoor athletics hall.

Arena-Sportpark occupies the grounds of the Rheinstadion, Düsseldorf's former main stadium, which was demolished in 2002. The park took over all the sports areas that had belonged to that stadium. Its athletics hall and the Kleine Kampfbahn, named to distinguish it from the former main arena, now form the core of the 95,000 m² site.

The park is used by amateur and leisure athletes as well as competitive squads, among them the Düsseldorf Panther, Fortuna Düsseldorf and ASC Düsseldorf. In summer, from 1 April to 30 September, the Kleine Kampfbahn hosts events ranging from school sports festivals to American football games.

The park is open daily and has parking available near the neighboring stadium. Visitors should check in advance which areas are open to the public, as many facilities may be reserved for training groups.

The Kleine Kampfbahn takes its name from the former Rheinstadion, once called the Hauptkampfbahn. Its covered grandstand holds 195 seats and 1,350 standing places, and from 1 April to 30 September it hosts events ranging from school sports festivals to American football games.
