The area is part of the Environmental Protection Area (APA) of the Whale Route, designated to protect the migratory corridor of Southern Right Whales.
The dunes at Siriú are among the tallest in the region and are protected by local environmental laws to prevent erosion and habitat destruction.
The Siriú River empties directly into the sea, creating a brackish zone that supports diverse local bird species.
The beach is one of the few places in Santa Catarina where freshwater river swimming is available just meters away from the ocean surf.
Siriú Beach is located in Garopaba, Santa Catarina, and is notable for the immediate proximity of the Atlantic Ocean to the freshwater Siriú River lagoon. The site features extensive sand dunes that are frequently used for sandboarding. The beach is characterized by its strong surf, making it a regular destination for experienced surfers. During the southern winter and early spring, the coastal waters are a primary location for the sighting of migrating Southern Right Whales. The landscape is largely preserved, maintaining a rugged and natural character with minimal high-density development directly on the beachfront. The Siriú lagoon provides a calmer, shallow alternative to the rough ocean waves.
