Plitvice Lakes National Park is the oldest and largest national park in the Republic of Croatia. With its exceptional natural beauty, this area has always attracted nature lovers, and it was declared the first national park in Croatia on April 8, 1949. The process of sedimentation, which forms travertine barriers and creates lakes, is responsible for the current appearance of the lake system. The lake system (16 lakes) is divided into Upper and Lower Lakes. It is an extremely complex biodynamic process, and the fact that the process continues today speaks to the pristine ecological conditions and represents a unique universal value for which Plitvice Lakes have received international recognition by being inscribed on UNESCO's World Heritage List.
Plitvice Lakes National Park is an area of rich forest and meadow habitats with diverse and abundant flora and fauna. Forests cover almost 80% of the park's surface. In terms of biodiversity, Plitvice Lakes National Park is one of the most valuable areas in Croatia, where a significant portion of the population of many species threatened at the national and global level still has sufficiently preserved habitats.
