The Maximilianpark was the location for the first Regional Garden Show in North Rhine-Westphalia in 1984. Wild meadows and areas of woodland form a contrast to the display areas of roses, perennials and shrubs. This dichotomy can also be found in the relationship between the buildings and landscape. The greened ecological building contrasts sharply with the section of the former coal washing plant boldly reconceived as an elephant by the artist Dr. Horst Rellecke.

The paths in the park run through various themed gardens, pass by seasonally changing plantings and through rugged woodland, continue past an area of semi-natural ponds and marshland and finally arrive at the lake terraces of the Maximiliansee with its fountains.

Many objets d'art enhance the park today. Themed playgrounds have been built for children while water can be experienced in its many different forms. Tropical butterflies fly through the air in the largest butterfly house in North Rhine-Westphalia.

The latest highlights in the park are plantings of perennials and grasses by garden architect Piet Oudolf. These invite the visitor to enjoy floral excursions through a sea of impressive plant compositions.
