This study explores the rediscovery and promotion of the lost cuisines of the Himalayas, focusing on their cultural significance, traditional culinary practices, and potential for sustainable tourism. The unique geography and cultural diversity of the Himalayan region have given rise to distinct food traditions, deeply embedded in the local environment and history. However, modernization, globalization, and shifting socio economic conditions have increasingly threatened these practices. This research aims to document and preserve the traditional culinary heritage of the region, while examining how it can be integrated into sustainable tourism strategies. Utilizing qualitative research methods, including interviews with local community members and tourism stakeholders, field observations, and a review of secondary literature, the study investigates the role of food in maintaining cultural identity and supporting local economies. The findings suggest that traditional Himalayan cuisine, characterized by its use of locally sourced, organic ingredients and sustainable practices, aligns with the growing global demand for eco-friendly tourism and wellness experiences. The study identifies challenges, such as the risk of cultural commodification and the need for infrastructure development, but highlights the significant potential of culinary tourism as a tool for cultural preservation and economic empowerment. By promoting traditional food practices within a sustainable tourism framework, local communities can benefit from increased revenue while safeguarding their cultural heritage. The research concludes that rediscovering the lost cuisines of the Himalayas offers a valuable opportunity to preserve cultural traditions, promote sustainable development, and create meaningful tourism experiences that benefit both visitors and local populations.
