Sierra de Capivara National Park, Brazil - UNESCO World Heritage Site

 Place: Sierra de Capivara National Park, Brazil

Weather: Sunshine and clouds mixed, 72/90F.

Route: From Sao Luis 918 km south on BR-135.

Significance: There are many decorations of ancient rock art, some painted over 25,000 years ago. Some of the examples of rock art seem so vibrant and energized - you can see movement in the scene that they depict.  There are also many archaeological sites older than the cave paintings, suggesting that humans arrived here as far as 50,000 years ago.
