Even though Sao Paulo is a huge concrete jungle of high rise buildings & apartments & traffic, & slums, ... it does have some nice parks and other nice places to visit. One of these places is the Sao Paulo botanical gardens, which is located in a large park complex that also includes the zoo and a safari type drive through zoo. The botanical gardens has many beautiful tropical plants & trees & flowers, and also has a couple of large ponds, and other nice things. One of the best parts is the jungle trail, which is an elevated wooden walkway through the jungle forest. If you go at the right time (early morning or late afternoon) you can see wild monkeys in the trees. You would never know you are in the middle of the city. Nancy and I and our son Daniel visited there yesterday.
