The Plitvice Lakes are the first and largest national park in Croatia, founded to protect the phenomenon of creation of travertine barriers, which creates lakes. They are located in the area of Lika-Senj and Karlovac County, between Mala Kapela and Lička Plješivica. The great value of this area has also been confirmed by UNESCO, by incorporating it into the World Heritage List. The tourism valorization of the National Park is based on preserved nature and biodiversity, as well as on the cultural and historical heritage of the Park and its surroundings. The main attractions are the Upper and Lower Lakes, 16 of them in total. Tourism has begun to develop in the second half of the 19th century, with the construction of the first accommodation facilities, and today it has grown into a mass tourism form. Such exploitation of protected natural space leads to many problems that could endanger everything that Plitvice Lakes tourism is based on. For this reason, it is necessary to change the way in which tourism of the Park and settlements around it operate. Above all, this would be achieved through the exploitation of opportunities for the development of selective forms of tourism, the enabling of authentic and quality experiences and the limitation of the number of visitors.
