Generation Z is transforming tourism by demanding the cocreation of transformative experiences. Cultural heritage professionals must comprehend the needs and desires of the Gen Z to support the cocreation of transformative experiences. This study analysed the role of Mixed Reality (MR) from the perspective of Gen Z guests through 18 semi-structured interviews and inductive qualitative research. Participants believe that cultural heritage experiences can benefit from immersive technology. Technology supports cocreation of experiences between developers, service providers, DMOs, and consumers. Cultural heritage sites, as a key element of tourism destinations, should consider how to use MR to enhance consumer experiences. Participants express the opinion that cultural heritage sites and tourism destinations require considerable modernisation to create transformative experiences. Metaverse in tourism and cultural heritage sites will undoubtedly support Gen Z to cocreate transformational experiences.
