The last owners of the castle, the Counts of Thurn, turned the fields behind the forest into a lovely castle garden with tall spruce, fir, pine, larch, maple, birch, lime, poplar, aspen and chestnut trees, as well as rare exotic trees and bushes. The entire park was designed and planted in a natural way, without any baroque elements, and it is characterised by its simplicity. It evokes a sense of relaxation and ease, and is reminiscent of lovely English-style parks, where nature is left to grow to its fullest potential. The park is crisscrossed and surrounded by many walking paths with benches nestled in quiet corners.

The park is now considered a monument to shaped nature and is the only major architecturally designed park surface in the Mežica Valley. The local people see it as an aesthetically decorative element of the town, a popular spot for daily rest and relaxation, and as the beautiful green lungs of the Mežica Valley. The original designer's exquisite feel for aesthetics and natural harmony is what attracts visitors from near and far.
The park is also a nice place to actively spend free time, go for walks, jog, and much more.
