Barequeçaba, Beach area in São Sebastião, Brazil.

Barequeçaba is a beach in southern São Sebastião with dense vegetation inland and a wide sand strip running along the shoreline. The seafloor deepens gradually from shore, creating different zones suitable for swimming and water activities, with small boat facilities nearby.

The name comes from the indigenous Tupi language and refers to a priest's sleeping place, reflecting its pre-colonial origins. This linguistic heritage preserves a connection to the region's original inhabitants.

The name Barequeçaba comes from Tupi: abaré (priest), kera (to sleep) and saba (place), meaning "place of sleep of the priest". A permanent population, many of them retired and elderly, keeps restaurants, shops and small marinas with boats to Ilhabela running all year, while a floating tourist population grows in summer.

The beach is located about 7 kilometers south of São Sebastião's center and is easily accessible. Restaurants, shops, and small boat docks are available, with regular connections to nearby Ilhabela.

The fire brigade, responsible for lifeguarding in Brazil, keeps a single guard at Barequeçaba even though other beaches have more than ten assigned, a ratio explained by the weak waves and the slow drop in depth. Entering about twenty metres, the water still reaches only the waist.
