The municipality of Caçapava do Sul is the geodiversity capital of Rio Grande do Sul State. This title is due to the scientific importance of its geological heritage. These characteristics allow the development of strategies associated with tourism and conservation. One of these strategies is the Geo.Dia. This project aims to promote the dissemination and valorization of the geological heritage of the municipality. Geo.Dia, held annually in November, since 2015, promotes activities in an outdoor square, as well as field trips to the three main geosites of the municipality. Because of this action, it is possible to envisage a greater insertion of the population in the context of geosciences. In the future, the Geo.Dia project can serve as one of the bases for a Geopark proposal.
