The east of the park was classified a Regional Nature Reserve in 1995. As a result, the site’s beauty has been both preserved and enhanced, allowing visitors to truly appreciate the natural space. 

Within the nature reserve there is a fishing lake, walking trails, farm and hunting lodge, as well as the "Asnapio" archaeological reconstruction park. Many of the pathways were redesigned in 2004 to provide a better understanding of the different living environments, flora and fauna.
