Spiritual tourism, through the integration of cultural and spiritual elements, promotes travelers’ mental health and has emerged as a new model of service that complements traditional mental health treatments; however, this model lacks a focus on the specific characteristics and needs of the youth demographic, as well as a design perspective, which may contribute to the inability to provide long-term mental health support for youth due to insufficient social support. Therefore, this paper explores the ways in which service design can foster long-term mental health support for youth in spiritual tourism services. The paper begins with a theoretical analysis to identify the key characteristics and limitations of current spiritual tourism services while also addressing the principles of service design and the rationale for incorporating suburban experiential lodging as a case.
