Santa Barbara's Waterfall is located inside Kalunga's community that was a slaves refugee village in colonial times of Brazil. Now the visitor can go throw the community and pay for a local guide that's take you to a quick walk to see the waterfall. The clean and very blue water its a natural phenomenal create by the limestone in the ground and the light inside the crater. People say that is a magical place because there's a huge pink quartz buried all the area, but i'ts only a legend, or not.
