It is located in central Croatia at the borders of the Bjelovar-Bilogora and Sisak-Moslavina County. It is located in the middle of lowland and is bordered by Lonja and Ilova rivers. Thanks to its natural features, it was interesting from the earliest times so it was mentioned in the works of ancient Greek and Roman writers as "MonsClaudius".
It is covered with dense forests and in its lower regions with cultivated orchards and vineyards. The fossil of prehistoric elephant and rhinocero was found on the mountain in the bentonite clay mine in Gornja Jelenska. On Moslavina Mountain there are ruins of old fortifications, most notably Garić-grad, which was built by Viceroy Stjepan Šubić. There are bicycle paths and marked routes for hikers and picknickers.
Because of its landscape and biological diversity, it was named the first regional park in Croatia.
