Lonjsko Polje Nature Park is geographically located in the area of the middle course of the Sava River, about 75 km southeast of Zagreb.
In the area of the Park there are 14 rural settlements – Osekovo, Stružec, Čigoč, Kratečko, Mužilovčica, Suvoj, Lonja, Trebež, Puska, Krapje, Drenov Bok, Jasenovac, Košutarica and Mlaka.
Lonjsko Polje Nature Park is one of the largest and best preserved natural floodplains in Europe . Every year, the waters of the Sava River and its tributaries flow into Lonjsko, Poganovo and Mokro polje. Thanks to such periodic flooding, the Nature Park is a unique treasure trove of biological diversity not only in Croatia, but on the entire Old Continent.
Lowland floodplain forests of pedunculate oak and field ash represent the most representative deciduous forest complexes and on a larger scale – in the entire Western Palearctic.
This area is a habitat for more than two thirds of the total bird population in Croatia . Their stability depends on the preservation and compactness of large complexes of lowland floodplain forests and grasslands.
The area is also one of the most important river fish hatcheries in the entire Danube basin. Ecological processes and flood dynamics have shaped a specific way of traditional land use by creating a unique mosaic of anthropogenic and natural habitats important for the conservation of biological and landscape diversity.
Opening hours for visitors are Monday to Friday from 9 a.m. to 5 p.m., and on weekends and holidays from 10 a.m. to 6 p.m.
