After the opening of the spa, tourism gained momentum. The city became one of the members of the "Região Turística da Serra do Itaqueri" (Touristic Region of the Itaqueri Ridge), composed of twelve municipalities. With the large influx of tourists, the need developed for improvements in the commercial sector, prompting renovation of the "Rua do Comércio" (Trade Street, old nickname for the street João Batista Azevedo).
