The Rio de Janeiro Carnival is a world-famous tourist event which brings crowds of Brazilians and foreigners together. the central parade takes place in the Sambodromo, located on Av. Marques de Sapucai, in the neighbourhood Cidade Nova in the north of the city. The samba schools that participate are divided into six categories, and in each category there are six schools. There are four days of parades. Even if you're not a member of an official school, you can dress up and participate in the parades, but this can be exhausting, as most people who do so have trained for a long time. Some tourist companies can help you to register for it, but just watching the spectacle will leave you speechless.
