Sustainable tourism has become a paradigm for the development of a community at a global scale. For this reason, the objective of this work was to build strategies for the sustainable management of tourism activities in the Manglar Route located in the Costa Rica community in Ecuador. First, a diagnosis was carried out to analyze the current situation of the tourist area, which implied the three dimensions of sustainability (economic, social and environmental). Second, tourists’ expectations were analyzed to design strategies adapted to the tourists’ expectations. The strategies were defined under the principles of sustainability; for that, participatory techniques were implemented by the active participation of the community. Nine strategies were established which are mainly based on improving tourism activity; the quality of service; training the population in tourism and environmental issues through articulated work between institutions. The strategies proposed contain nineteen projects to respond to the problems and needs of the area. The implications of this study demonstrated the importance of sustainable strategies for the tourism development of the Manglar Route.
