The Lika-Senj County, as largest county in the Republic of Croatia, is rich in natural and cultural values, with a large proportion of the area under different types of protection. The most famous protected area, also the largest attraction in the County, is Plitvice Lakes National Park, which, in addition to being the oldest and also the most popular national park in Croatia, is listed on the UNESCO World Heritage List. Tourism in the Plitvice Lakes National Park is constantly increasing, both in terms of arrivals and room nights, which has a positive effect on economic development and the standard of living within and around the Park. Unfortunately, this positive impact is maintained in the locations close to the Park and does not have as much impact on the entire Lika-Senj County. For this reason, this paper, through quantitative and qualitative analysis, provides an overview of the situation of the entire Lika-Senj County, the Plitvice Lakes Municipality, as well as the activities of the Plitvice Lakes National Park in order to identify opportunities to better link the supply of Lika-Senj County and the demand created by visitors of National Park. The analysis of the situation of the County of Lika-Senj and the Municipality of Plitvice Lakes, is based on the Guidelines for the Development of County Development Strategies Monitoring and Evaluation of their Implementation and is divided into three parts: society, economy and environment. In this way, by analyzing the current state of society, economy and the state of the environment, a clear picture of the County of Lika-Senj, the Municipality of Plitvice Lakes and the National Park of Plitvice Lakes has been obtained, which is the basis for understanding the existing situation and the dynamics of their better connection with the aim of better sustainable development of the County of Lika-Senj with the increasing role of the National Park in it.
