The beach is a protected part of the Baleia Franca (Right Whale) Environmental Protection Area.
The dunes at Siriu are among the most significant mobile dune systems in the state of Santa Catarina.
The Siriu stream serves as a natural nursery for various local fish species before they enter the ocean.
The beach serves as a seasonal observation point for Southern Right Whales, typically seen between late winter and early spring.
Praia do Siriu is located in Garopaba, Santa Catarina, distinguished by its massive sand dunes that descend directly into the Atlantic Ocean. The beach is situated within the Environmental Protection Area of the Baleia Franca, a sanctuary for southern right whales. The landscape consists of a long, open stretch of coastline characterized by powerful surf and a wild, undeveloped shoreline. A unique geological feature is the Siriu stream, which flows into the sea, creating calm freshwater pools ideal for swimming. The area remains significantly less commercialized than the neighboring central beaches of Garopaba. High coastal winds frequently shape the dunes, which are a primary destination for sandboarding. The beach faces east, providing clear views of the open ocean. Access is primarily achieved through the coastal road connecting Garopaba to Paulo Lopes.

Bring a sandboard if you intend to use the dunes, as equipment rentals are not always available on-site.
Pack all necessary supplies, including water and shade gear, as there is minimal commercial infrastructure directly on the sand.
Use strong sun protection, as the white sands reflect high levels of UV radiation.
Do not attempt to drive vehicles onto the dunes, as this is ecologically damaging and strictly prohibited.
Practice leave-no-trace principles to protect the sensitive dune ecosystem.
