On the grounds of the inn there was already a fairground with carousel, shooting dice and stalls, and a water slide, where a similar pontoon-like barge rolled down the mountain into the lake.

On 14 May 1909 the gourmet August Aschinger together with the former chef at the Kempinski Hotel, Bernd Hoffmann, opened the terraces at Halensee, which were renamed that year Luna Park.

It had as a special feature a water chute, which the Berliners called the "tart aquarium" because the ladies in the newest bathing attire presented themselves to the sitting gentlemen on the rim.

Following the example of Coney Island in Brooklyn, New York, an amusement park was established, offering sensations, adventures, and dangers, as well as the illusion of the big wide world and the experience of the seemingly limitless possibilities of technology.

Luna Park offered anthropological human shows ("Völkerschauen"); an early escalator; a large, nightly fireworks display; theater, revues, jazz, and cabaret; dance tournaments, and boxing matches.
