The beach is named 'Laboratório' because it was historically used as a primary base for the personnel and research teams during the initial construction of the Angra nuclear reactors.
Access to the beach is occasionally restricted or prohibited based on the operational security levels of the neighboring nuclear power plant facilities.
The beach serves as a protected sanctuary for local marine species due to the restricted maritime traffic in the immediate bay area.
The surrounding area was designated for industrial use in the 1970s, which paradoxically protected the local coastline from the mass real estate expansion seen in other parts of Angra dos Reis.
The geological composition of the beach features a blend of fine quartz sand and surrounding crystalline rock formations characteristic of the Serra do Mar coastal range.
Praia do Laboratório is a secluded beach situated within the complex of the Admiral Álvaro Alberto Nuclear Power Plant in Angra dos Reis, Rio de Janeiro. Its distinctive feature is its restricted and highly controlled access due to its location on federal property managed by Eletronuclear. The beach is known for its calm, crystal-clear waters and white sands, protected from the open ocean by the surrounding topography of the Itaorna region. It remains one of the few points along this stretch of coastline that experiences minimal commercial development. Visitors often encounter strict security protocols before reaching the sand. The environment is maintained as a preserved area, reflecting the natural ecology of the Ilha Grande Bay region.

Check local operational notices from Eletronuclear before planning your visit, as security protocols can close access without public warning.
Bring all necessary supplies, including food and hydration, as there are no commercial kiosks, restaurants, or infrastructure on the beach.
Ensure you have a government-issued photo ID, as it is mandatory for passing through security checkpoints leading to the coastal area.

Access may be suspended indefinitely for security reasons or maintenance activities at the nuclear complex.
Standard beachwear is appropriate; however, visitors must follow instructions from security personnel and refrain from wandering into restricted power plant zones.
