Spiritual tourism has developed significantly through creative activities such as the Bali Spirit Festival in Ubud, Bali. The aim of this paper is to analyse the practice of Bali Spirit Festival and its prospects for supporting tourism sustainability. The research design is descriptive-analytical and based on qualitative data. The data collection was done through in-depth interviews and a study of the literature. The research results reveal that spiritual tourism is oriented toward self-development based on religious values, culture, and nature without being exclusively tied to a specific religion. Further, the principles of spiritual tourism in Bali Spirit Festival can contribute to socio-cultural, environmental, economic and institutional sustainability.
