In 2012, Rio de Janeiro had a record of 5 million revelers at the Street carnivals, making it the largest FREE carnival in the world.
Only one of them, the centenary "Cordão de Bola Preta" , dragged more than 2.2 million people in one afternoon, in the launch of the Rio Carnival.
We will soon publish the official list of Blocos for the 2013 street carnival.
