Tourism development is linked to community-based transformation and growth, impacting the residents’ livelihoods. The study aimed to comprehensively understand locals’ perspectives on tourism development. The study mainly focused on identifying the factors that influence these perspectives and assessing their implications for sustainable tourism planning and management, using Yaoundé in Cameroon as a case study. Employing a quantitative survey research design, the study collected data from 385 locals using non-probability convenience sampling. Key findings revealed that positive perceptions of tourism development are linked to benefits. As residents benefit economically and socially from tourism, they desire increased tourist arrivals and see tourism as having positive impacts. A gap between training and participation in conservancy was identified, suggesting a major implication of the need to incorporate local voices in tourism planning and policies for more sustainable and inclusive growth of the tourism industry. By exposing factors that influence locals’ perspectives and assessing the implications for sustainable tourism management and planning, the study contributes to the literature and provides valuable insights to inform decision-making in the tourism industry.
