This paper explores the impact of maritime and coastal tourism on local communities, with a particular focus on sustainable development. Maritime and coastal tourism is crucial for both tourism and the economy, with rapid development that requires careful consideration from a sustainability perspective. The goal of sustainable development is to enhance the quality of life for local communities and future generations, taking into account ecological, economic, and social dimensions. Data was collected through a survey investigating local residents' perceptions of ecological challenges, economic benefits, and social changes. The findings indicate that tourism contributes to economic growth and employment, but also exerts pressure on local resources, increases property prices, and necessitates additional infrastructural adjustments. Respondents recognize the importance of environmental conservation and emphasize the need for concrete actions such as improved waste management systems and protection of natural resources. Additionally, there is a need to regulate tourism activities to maintain the quality of life for local residents, including greater involvement of local communities in decision-making processes, engagement of local producers, and promotion of education and sustainable practices in tourism.
