Laboratory Beach, Beach near nuclear power plant in Angra dos Reis, Brazil

Laboratory Beach is a small beach in Angra dos Reis, Rio de Janeiro state, pressed against the Almirante Álvaro Alberto Nuclear Center. It is also called Praia Secreta and is watched over by plant security guards. Access is from the Rio-Santos Highway, turning right just after the nuclear complex entrance when heading toward Rio de Janeiro, down a short descent.

The beach takes its name from an old laboratory that operated on the site, linked to the Almirante Álvaro Alberto Nuclear Center, the nuclear complex it adjoins. The sources give no founding date for the laboratory. Because of this association the beach is also called Praia Secreta, the Secret Beach.

The beach is also called Praia Secreta, a name that reflects its position beside the Almirante Álvaro Alberto Nuclear Center. Security guards from the plant watch over the sand, so bathers share the shore with a restricted industrial site rather than an open resort.

To reach the beach, turn right off the Rio-Santos Highway (BR-101) just after the entrance to the Nuclear Complex when heading toward Rio de Janeiro, then take the short descent. Security guards from the nuclear plant monitor the area, so access may be restricted.
