It has been proved for countless number of times, including the case of Goč Mountain, that consulting geographers for various questions is obligatory. The topic of this work is the necessity of establishing borders in mountain regions and ways in which it could be performed. It also points to the fact that toponyms could create confusion. The results of the paper have led to paradox situation. By establishing borders of the Goč Mountain, it has been proved that certain, terrains close to it, which were considered to belong to Goč, are in fact on the slopes of the other mountain, and in addition to it, between them there is one more lower mountain. Namely, it is interesting that conducting an interview among local population in southeast part of the mountain contributed to the process of confirmation of the border established by applying geographic knowledge, while on the southwest part of the Goč Mountain it was not the case. Additional analysis gave the explanation for the diversity. There is no local population in southwest part of the Goč Mountain. Interview was conducting between employees in tourist facilities, forestry workers and weekenders
