This study examines motivations and on-site experiences of volunteer tourists who participate in volunteer tourism at the Home and Life Orphanage in Phang Nga province, Thailand. An interpretive paradigm using qualitative data collection methods (semi-structured interviews, a focus group, participant observation, and diaries) was adopted. The informants included 24 volunteer tourists. The findings of the study suggest that the volunteer tourists’ motivations and on-site experiences are multidimensional. Five main themes of motivations have been identified: (a) to help the children who were affected by the 2004 Boxing Day tsunami, (b) to gain personal development and growth, (c) to gain new experiences, (d) to learn about/be immersed in local culture, and (e) to meet and make friends. In terms of the volunteer tourists’ on-site experiences, four experiential dimensions were found: (a) personal development and growth, (b) social, (c) cultural, and (d) feeling.
