Community participation has emerged as a cornerstone of sustainable destination development. As tourism expands globally, the involvement of local communities in decision-making, planning, and benefit-sharing is increasingly recognized as essential to maintaining cultural integrity, preserving natural resources, and ensuring inclusive economic growth. This research explores the role of community participation in destination development through qualitative and quantitative evidence from case studies, surveys (N = 550), and interviews with tourism stakeholders. Findings highlight that when communities are engaged in governance, tourism projects achieve higher levels of sustainability, visitor satisfaction, and socio-economic equity. Conversely, lack of participation leads to conflicts, resource mismanagement, and cultural degradation. The study proposes an integrated community participation model and outlines effective strategies for enhancing local engagement in destination development.
