São Paulo has the best metro in Brazil. For 1.40 reis you can go from one side of the city to the other. There are stops everywhere, from the airport, the bus station, and all points of interest. If you but the multi-pass the price is even cheaper. I never had any problem on the metro either, but it is probably a good idea to leave your expensive jewelry at home, but that is good advice all over Brazil.
São Paulo has a Metrosystem, which is only good for the very center. But it is better to leave the car outside the Centre (on a place with security)(for Example Jardins Paulista) and take the Metro which is safe during the day.
But be carefull if the train is full (pickpocket)
the Metro is one of the cleanest and most efficient I've ever seen, but unfortunately it's not so expansive . the Bus services the rest, but people told me that it could get very dangerous to ride the bus at night. Learn enough Portuguese to negotiate with a taxi driver; it's completely stressful if you don't!
This is a sprawling city, and cars rule okay? But underneath the city is a fairly extensive underground metro which would take you to some of the more important places in Sao Paolo. It 's quite cheap too, but avoid it at rush hour for it gets too close for comfort.
Getting around Sao Paulo is easy! Get the metro and you won't be disappointed. Just make sure you prepare to face the buzz of one of the most modern and hectic major cities in the world. Avenida Paulista, picture on the left, is an example of how this city never stops!
The metro is great. It takes you pretty much everywhere you need to go. Fast, clean, safe, and efficient. The major bus stations (Terminal Rodoviário - for destinations in other parts of Brazil) are situated at metro stations. There are several bus stations around the city, so be sure to know which station your bus is leaving from and at what time!
São Paulo's metrô is clean, quiet, and fast, and the easiest way to move around the city; however, it is limited to just three lines. Because of this the travel capabilities are truly limited; if you can use it to get where you want to go, though, it's great. You can also buy integrated bus/metrô tickets, as many buses stop at the metrô stations, with the names of their destinations well marked.
Stations: The north-south line has terminals at Santana and Jabaquara (the Rodoviária from where buses to Santos depart) and also serves the Tietê Rodoviária and Luz train station. One of the east-west lines has terminals at Corinthians-Itaquera and Barra Funda, and intersects with the north-south line at Praça da Sé. The shorter east-west line crosses underneath Avenida Paulista from Ana Rosa to Clinicas stopping at the Museu de Arte (Trianon-Masp station).
This is more than just a metro map; actually it's a complete tourist map with all major attractions written in Portuguese.
