Sport participation and physical activity promotion have been intensively studied, especially regarding large cities. However, in many cases, rural municipalities have comparatively reduced services, including health care, due to the low profitability that these have for companies and entities. In this sense, the purpose of this article was to describe a case study of the promotion of physical activity in rural areas based on the results of a European project. Carried out in a rural municipality of around 8500 inhabitants with a population density of less than 25 inhabitants/km2 , the project’s purpose was the promotion of autonomous physical activity among its inhabitants. For this, a diagnostic analysis of the sports areas of the environment and a survey of physical activity habits among the population were carried out. A series of routes were designed, marked, and signposted, and canopies with explanatory posters about the possibilities of healthy physical activity and recommendations were added. Free-use facilities were installed, and opening events were carried out in such a way as to stimulate sports practice among the population. This article presents the results obtained from the analysis, as well as the possibilities of replication in other municipalities with similar needs.
