|Considering trail settings in alpine national parks is important for both conserving nature and maximizing the quality of the experience for visitors. This study examines classifying trails in Daisetsuzan National Park, Japan, using the Recreation Opportunity Spectrum approach. A questionnaire was used to obtain data from park visitors concerning their preferences for the facility developments, accessibility, and visitor encounters. The responses were classified into four groups according to the preferences expressed for the types of trail settings. The trails were classified according to their characteristics as described by park visitors. The northern part of the park, with easier access and moderate development, was preferred by all groups, and the southern part of the park was preferred only by the those who favored more primitive surroundings.
