This study aims to develop a cultural heritage–based tourism package in Pontianak City to optimize the potential of its historical and cultural assets. Pontianak possesses rich heritage resources, including the legacy of the Malay Sultanate, Dutch colonial architecture, and Chinese cultural traditions that reflect its multicultural identity. The research employed a descriptive–qualitative approach using the 4-D development model (Define, Design, Develop, dan Disseminate) through field observation, in-depth interviews, and document analysis from cultural heritage institutions. The findings identified and classified heritage sites into three main clusters: the Sultanate Cluster, the Dutch Colonial Architecture Cluster, and the Chinese Heritage Cluster, as well as an additional cluster, the Pontianak City Heritage Street Corridor. Based on the 6A Tourism Model (Buhalis, 2000), two thematic tour packages were developed: The Colonial Heritage and City Story Trail and The Kapuas River Trail, both designed to offer educational, interpretive, and sustainable cultural experiences. As a continuation, this study recommends developing a Heritage City Tour Catalog as an interpretive and promotional medium. The research provides a model for urban cultural heritage tourism that strengthens local identity and supports community-based creative economies.
