The rapid urbanization that has occurred in Bulukumba Regency has resulted in a significant decrease in the area of green open space (RTH), due to uncontrolled land conversion. Indeed, the presence of green spaces is imperative for maintaining the balance of urban ecosystems, reducing the impact of climate change, and enhancing the quality of life for the community. This study aims to analyze the potential, constraints, and strategies for developing ecotourism based on green spaces in urban areas of Bulukumba Regency. The research method employed was a descriptive, qualitative, and quantitative approach, encompassing field surveys, spatial analysis using Geographic Information System (GIS) technology, and interviews with a diverse array of stakeholders. The findings of this study indicated that Bulukumba Regency possesses considerable potential for the development of green open space-based ecotourism, encompassing urban parks, urban forests, and community-owned mixed gardens. However, various obstacles have been identified, including the absence of adequate supporting facilities, limited public awareness regarding the significance of conservation, and insufficient budgetary allocations from the local government.
