Hopi Hari
One of the largest and modern amusement parks, the Hope Hari is actually divided into five separate parks and is located about one hundred kilometers from Sao Paulo. You can either drive there, (which takes about an hour), or you can take a bus to the park. Their website is mainly in Portuguese but your hotel staff will be able to guide you.
