The purpose of this study was to examine the environmental and ecotourism impacts of the Khuvsgul region in Mongolia and to suggest some implications for tourism policy in the development of ecotourism in Mongolia. For this purpose, a questionnaire survey was conducted to the residents of Khuvsgul. The results of the analysis are as follows. First, differences appeared depending on the demographic characteristics of the Khuvsgul area residents; particularly, men had a higher awareness of the natural environment, and women were more likely to be in harmony with nature. Second, women were more likely to be eco-tourism-influenced by men. For the occupational group, public officials perceived more negative economic aspects than other occupational groups. This seems to be more sensitive because officials are responsible for directly managing the occurrence of various regional problems. Finally, it was found that balance (harmony with nature) lowers the adverse effects of ecotourism. This is because proper tourism development recognizes that the environment of the area should be preserved and should contribute to regional development. Therefore, ecotourism in Mongolia would be necessary not only for economic benefits but also for minimizing environmental damage based on conservation. Until now, various development including tourism has not been able to occur harmoniously with the environment, and negative influences can be seen in the Khuvsgul region. In the future, various efforts will be needed to ensure that ecotourism has an appropriate balance with the natural environment of the area. In particular, it is necessary to establish a system in which local residents can participate as a subject, not as an object, of local tourism. Various efforts will be needed to make the system and development necessary for tourism development. natural environment of the area.
