In Ubatuba remains a place were slaves used to prepare flour for their masters. Brazil was one of the lasts countries in the world to abolished slave work, only in 1888. So many children's of former's slaves still alive. One of them is Mr Pedro, and he's there everyday to receive tourists and tell a little bit of his story and his family.
As a bonus, visiting this place, which is free entrance, you can walk until a beautiful waterfall, as seen on the picture below.
