The ecosystem services (ESs) approach has been used as a powerful tool for the analysis of socio-ecological systems to investigate the relationship between society and the environment. The aim of this article is to analyze the social perceptions of stakeholders, forms of use (sociocultural and economic), and the conservation of beaches and coastal dunes in Yucatán, Mexico. Interviews were held with focus groups to analyze the forms of use, social perceptions of stakeholders, and the conservation of beaches and coastal dunes in Yucatán, Mexico. The results indicate that these ecosystems are important to different types of activities related to regulating, provisioning, and cultural services. However, degradation is identified as a consequence of contamination and land-use change. The main identified threats are natural phenomena, followed by the presence of garbage, human presence in natural environments, infrastructure construction, and privatization of beaches. The opinions (e.g., conservation, ecosystem services provision, drivers of change), emotions (e.g., joy, fear, sadness), and knowledge of the local community and tourists with respect to these ecosystems were evidenced. In general, there is an absence of conservation and sustainable management projects. However, community perceptions provide an opportunity to outline public conservation strategies in which the community, as a component of these socio-ecosystems, can be fully involved in their implementation.
