Research on sustainable tourism in Bali has underscored the intricate balance required between economic development and environmental and social stewardship. A range of methodological approaches has been utilized to evaluate these dynamics. Quantitative assessments, often through structural equation modeling, have been conducted to analyze sustainable tourism practices, focusing on economic, social, and environmental dimensions. Meanwhile, qualitative approaches, including systematic literature reviews, semi-structured interviews, and participatory observation, have provided critical insights into the layered complexities of sustainable tourism in Bali’s culturally rich settings. Mixed-methods research, integrating quantitative tourist data with qualitative insights, offers a more comprehensive understanding of overtourism’s multifaceted impacts. Key findings indicate that while progress has been achieved in implementing sustainable tourism practices, considerable challenges remain. These challenges primarily include balancing the economic benefits of tourism with the urgent need for environmental conservation and ensuring equitable distribution of benefits among local communities. The development of sustainable tourism has proven complex, necessitating context-sensitive approaches and inclusive stakeholder engagement. Community-based strategies have shown effectiveness, blending environmentally friendly practices with cultural preservation and local empowerment. Comparative studies, such as those between Bali and North Sumatra, underscore both the positive economic outcomes of sustainable tourism initiatives and common obstacles, such as infrastructure demands and resource management. The implications for policymakers emphasize the critical role of community participation and comprehensive planning in achieving sustainable tourism. Empowering local stakeholders through participatory governance frameworks is essential to preserve cultural integrity and enhance resource stewardship, thereby fostering a resilient tourism industry that supports both environmental sustainability and local well-being.
