The municipality contains part of the 84,130 hectares (207,900 acres) Serra do Tabuleiro State Park, a protected area created in 1975. The lushly-forested park protects the sources of the Vargem do Braço, Cubatão and D'Una rivers, which supply most of the drinking water for greater Florianópolis and the south coast region.
