Praia do Monduba, Beach in Guarujá, Brazil.

Praia do Monduba is a beach about 400 metres long inside the grounds of the Forte dos Andradas, in the municipality of Guarujá. The site also houses the 1st Anti-Aircraft Artillery Brigade, the headquarters of the Brazilian Army.

Praia do Monduba lies inside the grounds of Forte dos Andradas, which today houses the 1st Anti-Aircraft Artillery Brigade, the headquarters of the Brazilian Army. The beach, about 400 metres long, is reached only through this military installation, so the garrison's presence governs who can enter.

The beach serves as a gathering place where local families spend weekends enjoying volleyball, soccer, and picnics by the water. This everyday social life shapes the relaxed character of the location and shows how the community uses the space for recreation.

Entry to the beach requires prior authorization because it is located within a military facility managed by the 1st Anti-Aircraft Artillery Brigade. Visitors should arrange permission ahead of time before attempting to visit the location.

This location stands out because military training and leisure activities coexist in the same space, with soldiers exercising while swimmers enjoy the water and sun. This unusual combination creates an environment quite different from typical beaches.
