The purpose of this study is to present academic and practical implications for adapting to the changing environment as a study on wellness tourism selection attributes and behavioral intentions according to the characteristics of the MZ generation after COVID-19. The subject of the study was surveyed using a questionnaire for consumers who experienced wellness tourism, and finally, statistical analysis of factor analysis, reliability analysis, correlation analysis, and regression analysis was conducted based on 289 samples. As a result of empirical analysis, first, it was found that original selection, non-intermediate selection, and similarity avoidance, which are characteristics of the MZ generation, have a positive (+) effect on wellness tourism selection attributes. Second, it was found that the characteristics of the MZ generation, original selection, non-intermediate selection, and similarity avoidance, also had a positive (+) effect on behavioral intention. Third, it was found that the wellness tourism selection attributes, such as mental health pursuit, physical health pursuit, and emotional health pursuit, had a positive (+) effect. The implications of this were to develop wellness tourism resources differentiated from those affecting the expansion of subsequent studies on the relationship between the characteristics of the MZ generation, wellness tourism selection attributes, and behavioral intentions, and to have adaptability to the changing tourism environment and to revitalize the local economy
