The paper deals with the importance of tourism for the development of Lika-Senj County, as well as its cultural heritage, which should be developed as an important part of the tourist offer of the area. An insight is given into the possibility of using the cultural sights of Lika-Senj County, with an indication of certain localities that need to be valorized. The main obstacles for the future development of this area are also stated. The theoretical basis needed to understand concepts such as tourism, culture, cultural heritage, cultural-historical ensemble and the like is also analyzed. The main obstacle to the development of Lika-Senj County is the poor demographic structure of the population, but also their passivity towards any development of space. Examples of valorization of certain parts of cultural and historical units in Croatia and in the world are also processed, and on that basis it is compared with Lika-Senj County. Individual tourist trends are also presented in order to create an appropriate tourist offer of the county. It is concluded that Lika-Senj County has good cultural and natural resources for tourism development, but there are not enough educated staff to develop the tourist offer of this county. Some cities are not sufficiently developed for tourism, and there is no joint cooperation between them. Good promotion and employment of skilled labor in the field of tourism would encourage the tourism development of this county.
