Barra do Saí

Barra do Saí is a beach in São Sebastião where the Sahy River meets the ocean, creating clear waters framed by Atlantic Forest vegetation on the shoreline. The river mouth forms a distinct zone where fresh and salt water mix.

The Sahy River served as an important water route for early settlers in São Sebastião during the 16th century. This natural passage eased early trade and exploration of the region.

Fishermen here practice traditional methods passed down through generations, and their daily catch reaches beachfront restaurants where regional seafood dishes are prepared. You can watch this work happen directly along the shore.

The beach is accessible through a paved road off the BR-101 highway, with parking areas and basic facilities near the shore. Visitors should note the tidal cycles, as they greatly affect the water experience and the formation of natural pools.

At low tide, natural pools form in the river mouth area, creating protected swimming zones. These temporary basins shift with each tidal cycle, offering a different landscape every few hours.
