It's perhaps not surprising that the largest city in the Southern Hemisphere has an absolutely enormous and quite fabulous gay pride celebration each year, but the magnitude of the Sao Paulo Gay Pride Parade is still astounding. Brazil is still a predominantly Catholic and in some ways conservative country (although increasingly progressive when it comes to LGBT rights), and the city's Pride parade, known officially in Portuguese as the Parada de Orgulho GLBT de Sao Paulo and produced by the APOGLBT, only began in 1997, when it drew an attendance of a couple of thousand.
Fast-forward to 2011, and the parade drew nearly 4.5 million participants and spectators - it's now recognized by the Guinness Book of World Records as the largest Gay Pride celebration in the world.
Sao Paulo Gay Pride takes place in early June - the date this year is May 29, 2016, with related Pride events taking place the full week leading up. Additional festivities continue throughout the following month of June into early July.
The actual Sao Paulo Gay Pride Parade occurs on May 29, departing at 10 am. It commences outside the Museu de Arte Moderna de Sao Paulo (MASP), at Aveninda Paulista. The city absolutely pulses with parties, not to mention several related events, during the days leading up to Pride and throughout the weekend.
