The main purpose of the study is to identify and assess the main threats to the socio-economic development of the tourism business in the mountainous territories of Eastern Europe. We have applied the methods of synthesis, analysis, deduction, induction, mathematical methods, methods of expert research. The importance of research on the management of socio-economic development of the mountains in the conditions of increasing the efficiency of the tourism business is proved. Peculiarities of managing the socio-economic development of the mountains in the conditions of increasing the efficiency of the tourism business are considered. As a result of the study, threats were identified that most negatively affect the management system of the socio-economic development of the tourism business in the mountains. The novelty of the study is the formation of coordinate systems in the trust or distrust of the management and executive staff of travel companies in making management decisions.
