Serra do Tabuleiro State Park, State park in Santa Catarina, Brazil

Serra do Tabuleiro State Park covers 84,130 hectares across eight municipalities in Santa Catarina, including Florianópolis, Palhoça and São Bonifácio. It protects five of the six Atlantic Forest formations found in the state, from coastal restinga and mangroves to dense rainforest, Araucaria forest and high-altitude grasslands. The park also includes the Moleques do Sul archipelago and the southern tip of Santa Catarina Island.

The protected area was established in 1975 to safeguard water sources for regional communities and preserve forest coverage in a rapidly developing region. This early conservation effort protected a large ecosystem from destruction due to urban expansion and resource extraction.

Fishing families in the region continue traditional practices in designated areas of the park, maintaining ways of life that have shaped this landscape for generations. These activities remain deeply connected to both the forest and coastal zones that sustain local communities.

The headquarters and visitor centre are on the BR-101, 40 km south of Florianópolis in Palhoça, and opened on 6 June 1978. The centre has a conference room, a gazebo above the treetops and a 1 km ecological trail with guided tours. Two thematic centres are in Imaruí and São Bonifácio. The Praia dos Naufragados trail takes about two hours each way.

The Baixada do Maciambu formation displays circular sand ridges that document historical sea level changes across geological timescales. These uncommon formations give visitors insight into the coast's natural history and how the landscape has shifted over time.
