The promotion of tourism without planning or management can lead the degradation of ecosystems and conflictive social dynamics. This study was conducted in a coastal location where tourism has recently intensified and aimed to reconstruct the preliminary history of tourism and analyze which social groups were involved in tourism and conservation for conducting an ecotourism management. A qualitative content analysis was conducted based on the perceptions of developers, authorities, and tourists in the locality. The results identify social groups involved in the use of ecosystems within the context of local tourism, their interactions, interests, and actions. An analysis of actions contrary to the conservation of these ecosystems that cause land use conflicts and hinder the development of endogenous local tourism was conducted. Social movements and collective actions reveal common interests and values among the inhabitants of Sisal that reveal the potential for transformation into a sustainable tourism project for endogenous local development.
