Transformative tourism experiences result in long-term changes in attitudes and behavior. Although research on transformative tourism has flourished in recent years, there is still a limited number of studies that investigate the travelers' experiences to examine the impact of travel on one's attitudes and behaviors. This exploratory study seeks to identify factors affecting transformative travel experiences to emerge. A typology of travel transformations is also offered based on a qualitative case study conducted on Turkish travelers. As a result of thematic content analysis of in-depth interviews with 30 travelers, the main themes affectingtravel transformations emerged as tripograhic, personal and destination-based determinants, whereas the types of transformations were classified under behavioral, attitudinal, and personality changes. If tourist transformations could be understood better,this might result in better promotion of travel as a leisure activity not just at the individual level but at the policy level. Destinations, tour operators, and other hospitality organizations would position their product in a potentially more transformative way if they know the causes and outcomes of travel-related transformations
