This study aims to examine the motivation, experience and benefits of Nepalese domestic tourists visiting the seismic memorial sites after the 25 April 2015 earthquake (known as Gorkha earthquake). A total of 403 surveys was gathered from seismic sites of Nepal (Kathmandu, Bhaktapur and Patan). Data were tested to analyze why the tourists are interested in disaster sites and how their experience during their visit impact the benefits of the visits. Additionally, partial least square structural equation modeling (PLS-SEM) was employed to test the relationships among tourist motivations, experiences, and perceived benefits at the dark tourism sites in Nepal. Among the five motivational factors discovered, the empirical results depict that emotional reaction is the strongest factor of the dark tourism motivation, affecting both cognitive and affective experiences. Additionally, this study confirms that cognitive experience is more influenced by dark tourism motivations than affective experience. Among the four experience factors examined in the study, self-reflection is found to have the strongest impact of three aspects of perceived dark tourism benefits, such as knowledge gain, fulfillment, and appreciation. Overall, the findings of the study provide important implications to the management sectors of dark tourism sites, enhancing the importance of providing cognitive experiences (i.e. distributing the educational materials about the dark tourism events and offering the knowledgeable tour guide who can guide the sites) and affective experience of the tourists (storytelling about the events, organizing educational and volunteering programs at the sites). Further, this study contributes to the limited literature in the context of dark tourism and provide important managerial and practical implications based on the case of Nepal earthquake in 2015.
