Praia do Abricó:
Is the only official nude beach in Rio de Janeiro. The beach is enclosed by the lush Grumari Area of Environmental Preservation,
in the west of Rio de Janeiro, past Barra da Tijuca and Recreio dos Bandeirantes.
It is a nude beach, but do not think it is crowded with naked beautiful woman, mostly naked men masturbating.
I only noticed two naked women there in total the days I checked.
Reviews online shows this beach is supposed to be full of naked woman, but I have been there for several days and checked it out since the beach is just next to the ordinary beach of Grumari.
You should know that there are no Taxis going to this beach, so either you have to rent a car or you can contact Lapa Hostel for a day at the beach.
For a 100$ Reis you will get a minivan and a driver will leave you there and pick you up when you want to go back.
It takes about 1½ hours to get there from the center of Lapa.
Notice: The picture of Black Bar is not associated with the nude beach, but it is where you access the nude beach.
