The initial hypothesis of the work was the assumption that Zlatibor has potential for sustainable tourism development, but that the tourism destination Zlatibor is still not sufficiently competitive with the tourism destination Kranjska Gora. The research presents the key features of these areas, and their attractive tourism offers, through a comparative analysis. Also, this paper deals with the chances for the development of sustainable tourism, as well as the improvement of tourist services, specifically Zlatibor, bearing in mind that the Kranjska region is in a much better position, as far as the implementation of the concept of green tourism development. The research was conducted using a modified Integrated Model of Destination Competitiveness (IMDC) model, seeking responses from stakeholders from both Zlatibor and Kranjska Gora (259). Bearing in mind that the responses of stakeholders from Slovenia showed consistently higher values in the assessment of destination competitiveness, the starting hypothesis proved to be correct, and in response to that, guidelines were given for improving competitiveness and overcoming certain threats observed in the research results.
