Adventure tourism accounted for 60% of international tourism activities by the year 2007 and is still growing. Nonetheless, relatively little is known about the ecological issues associated with adventure tourism. To address this issue, this study examines 502 Chinese tourists’ intentions to revisit adventure tourism activities by incorporating nature-relatedness (i.e., NR-self, NR-perspective, and NR-experience) into a modified flow model. After analyzing these data by structural equation modeling, our findings show that positive emotions and flow experiences influence one’s intentions to revisit adventure tourism activities and that then intensity of the flow experiences is influenced by skill, perceived challenge, and playfulness. Moreover, our study finds that tourists who enjoy being outdoors (NR-experience) and who find conservation unnecessary (NR-perspective) are likely to have a more positive attitude about adventure tourism. Conversely, individuals who are concerned about the environment will not have such emotions. The implications of these findings for such promotions are discussed.
