This study analyzed the consciousness and attitudes of local residents to the development plan of Sobaeksan Jarackgil by applying the social exchange theory to provide basic data for the establishment of the Mountainous Ecology Trail Development Plan, collecting opinions of local residents. For this, we conducted a self-administered questionnaire survey and personal interview targeting 150 residents of seven villages. Summarizing the results, first, because of analyzing the consciousness of the residents, most of the local residents turned out to be aware of the Sobaeksan Jarackgil development plan and agreed on it. Second, as a result of analyzing the consciousness of residents, for attitudes according to gender, females expected more than males of exchanging with visitors and excavation of cultural assets. Furthermore for attitudes according to age, groups aged under 60 turned out to be concerned about the increase of environmental pollutions, rise in crimes, destruction of cultures, and the induction of conflicts among residents. For attitudes according to occupations, farm workers were worried about the destruction of ecology, and for local characteristics and damages to the landscape, all of the local residents turned out to be concerned. It was shown that groups that agreed on the development plan expected positively on most of the items of economic, environmental, and sociocultural aspects, while those that disagreed on the plan were anxious for negative effects such as landscape damages and the increase of environmental pollutions from the environmental point of view, and the induction of conflicts among residents from the point of sociocultural perspective.
