The Tiete River bank Park is great - wonderful trails, good picnic and barbecue areas, there is even row boats for rental.
However, the Tiete River is very polluted and during hot, dry periods the park can have a very unpleasant smell.
This amazing park was created in 1976,with the main objective of trying to maintain the waters of the Tiete banks on their borders,and avoid the many and tragic inundations of some areas in Sao Paulo city!
With the purpose of keeping in the minimum the problem of inundations,a huge new " green" area was created in the city,for the inhabitants fun!
Here you can find many species,including the "capivara ",what is much common here!
The Parque do Ibirapuera, a large grassy area, is Sao Paulo's major public park. Its lake is a refreshing presence, and the park's monuments add a touch of solemnity. But, the planetarium is what sets the park apart.

There is a poisonous animal park called Butãtã. Last time I was there it was a bit beat up looking. It would be worth a call to see if they've renovated the place. At the very least its a nice wooded area to stroll around in.
Spend the afternoon at the botanical garden. Nice plan layout with a wilderness area, so you can see what Sao Paulo would look like if it was not covered in concrete.
Take the Blue Line 1 subway to the end (Jabaquara), then jump in a cab. It's next to the zoo.
The park offers beautiful walking tracks,a library,an environment educational center,open theaters,a winter garden with many species of orchids,lakes and areas for barbecue!
The park can be consider as a big cultural and educational "lab",where people can relax and be in contact with nature at the same time!
