Cultural heritage is the sum of material wealth and spiritual wealth left by a nation in the past. Because of its precious and fragile characteristics, cultural heritage protection and tourism development have received extensive global academic attention. However, application visualization software is still underused, and studies are needed that provide a comprehensive overview of cultural heritage tourism and prospects for future research. Therefore, this research employs the bibliometric method with CiteSpace 5.8. R2 software to visualize and analyze 805 literature items retrieved from the SSCI database between 2002 and 2022. Results show, first, scholars from China, Spain, Italy have published the most articles, and Italian scholars have had the most influence. Second, Hong Kong Polytech University, the Chinese Academy of Sciences, Jinan University have had significant influence on cultural heritage tourism research. Third, Annals of Tourism Research is the most cited journal in the field. Influenced by politics, culture, and technology, sustainable development and consumer behavior have become key topics in this field over the past 21 years. Fourth, tourist satisfaction, rural development, cultural heritage management are the key research frontiers. Fifth, in future, cultural heritage tourism should pay more attention to micro-level research, using quantitative methods to integrate museums, technology, and cultural heritage into consumer research. The results offer a deeper understanding of the development and evolution of the global cultural heritage tourism field from 2002 to 2022. At the same time, our findings have provided a new perspective and direction for future research on global cultural heritage tourism among scholars. [ABSTRACT FROM AUTHOR]
