The beach is located at the mouth of the Saquarema Lagoon, which frequently experiences shifting sandbar formations due to tidal influence.
The intersection of the lagoon and ocean creates a distinct thermal gradient in the water, noticeable when swimming near the meeting point.
It is a primary access point for the world-renowned surf breaks of Itaúna beach.
The area is an important nursery for various estuarine fish species native to the Rio de Janeiro coast.
Praia da Barrinha is a unique coastal environment in Saquarema where the freshwater of the Saquarema Lagoon meets the saltwater of the Atlantic Ocean. The area is defined by the narrow sandy strip that separates these two water bodies, creating a calm, shallow lagoon side suitable for swimming. It serves as a major hub for regional surfing culture due to the high-energy waves prevalent on the ocean-facing side. The beach is bordered by a mix of residential structures and natural vegetation. It acts as an ecological transition zone for local aquatic species. The location is publicly accessible and integrated into the broader Itaúna coastline.

Check local tide tables as the currents at the lagoon mouth can become strong during high tide changes.
Bring specialized footwear if you plan to explore the rocky outcrops nearby.
Sun protection is essential as the beach has minimal natural shade on the sand.
Do not attempt to swim directly in the narrow channel where the lagoon exits into the sea due to unpredictable and powerful rip currents.
Standard beach attire; respect local surfing priority rules in the water; pack out all trash to protect the estuarine ecosystem.
