This paper deals with the sustainability of tourism in Stolovi Mountain. The purpose of the research was to show that it is possible to develop sustainable tourism in unestablished localities, intending to reduce differences in regional development in the Republic of Serbia, and then refine the tourist offerings of already established tourist localities in the vicinity. Various literature sources were used in the research. GIS software (QGIS 3.12) was used in order to create geographic and other special maps. Field observations were conducted, which were used to perform an in-depth analysis. In addition, two surveys were conducted with people from Kraljevo and those coming from other places in order to determine the identity and recognizability of Stolovi Mountain. The significance of this research is in pointing out that the connection of tourist sites can enrich the offer and attract new visitors, but also in supplementing scientific knowledge about Stolovi Mountain. The main results of the research show that green forms of tourism will ensure ecological sustainability. Kraljevo, a nearby city, is home to the workforce that will care for the localities, provide material contributions for the preservation of nature, guide jobs and sell souvenirs. Stolovi Mountain could quickly be included in various tourist tours and begin to demonstrate the first positive economic effects, followed by sociodemographic ones. The affirmation of mountainous, sparsely populated areas will lead to uniform regional development.
