Teak forests are critical ecological and economic resources that support biodiversity, carbon sequestration, and local livelihoods. This study examines the potential development and commercial enhancement of teak forests through sustainable ecotourism and community-based initiatives in Ban Tham Suea Community, Phetchaburi, Thailand. The research aims to evaluate the feasibility of integrating conservation, tourism, and community development, emphasizing environmental sustainability, cultural preservation, and economic empowerment. A mixed-methods approach was employed, combining surveys of 474 local residents and tourists, in-depth interviews with community leaders and stakeholders, and field observations. Quantitative data were analyzed using descriptive statistics, reliability tests, factor analysis, and inferential tests (t-test, ANOVA, chi-square), while qualitative data were analyzed thematically. Findings indicate strong potential for ecotourism development, supported by rich biodiversity, cultural heritage, and local interest in tourism activities. Challenges include limited infrastructure, insufficient marketing strategies, and gaps in community capacity. The study concludes that integrated planning, community participation, and sustainable management practices are essential to optimize both ecological preservation and economic benefits. The research contributes practical guidelines for policymakers, tourism planners, and communities seeking to implement sustainable tourism strategies in forest-based areas (Gossling & Hall, 2019; UNWTO, 2018)..
