Gay cruise bars and "gay play" parties
The Brazilian gay sauna culture is dominated by prostitution. Most of the time you can recognize them because the are far better looking and muscled than you do, and they wear a different color towel. However, there are hooker free gay saunas too. Rio de Janeiro have many gay saunas / bath houses (too may to mention). Nighttours made a selection of gay saunas in the tourist areas.
Maybe the most famous beach in the world. Not as gay as Ipanema, but enough to enjoy. [...]
