The subject of the final paper is focused on the development of tourism in the Plitvice Lakes National Park. In accordance with Croatian and international standards, Plitvice Lakes National Park is a very distinctive and protected area. The main activity of Plitvice Lakes National Park is the protection, maintenance and promotion of the value of this National Park in order to protect and preserve the originality of nature, ensuring the smooth running of natural processes and sustainable use of natural resources, and monitoring the implementation of protection conditions and measures. The tourist valorization of the Plitvice Lakes National Park is based on preserved nature and biodiversity, but also on the cultural and historical heritage located in the area of the Park and its surroundings. The main attractions are the Upper and Lower Lakes. The tourism of the Park began 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 form of tourism. Such exploitation of protected natural space leads to many problems that could jeopardize everything on which the tourism of Plitvice Lakes is based. For this reason, it is necessary to change the way tourism works in the Park and the settlements around it. First of all, this would be achieved by taking advantage of opportunities for the development of selective forms of tourism, providing authentic and quality experiences, and limiting the number of visitors.
