Trail degradations have been found in popular mountainous natural parks in Japan. For maintenance of trails, managers should pay attention to the attitudes of hikers and stakeholders, and they should get the consensus for the ideal maintenance method of trails with hikers and concerned stakeholders. The method that demonstrates projected trail maintenance method is needed. In this paper, we compared the hikers' evaluation of trail condition and the image of trail maintenance between on-site survey and mail-back survey at Daisetsuzan National Park, Japan. We also applied photo-montage method to evaluate projected trail maintenance by stakeholders using conjoint analysis. There were little differences between on-site hikers evaluation and mail-back evaluation. The results also didn't show any differences between labeled photos and unlabeled photos. The results of conjoint analysis showed that stakeholders considered the importance of limit of use level less than trail surface maintenance. Stakeholders preferred boardwalk at Susoaidaira where are flat and muddy area.
