Serra da Capivara

The canyon walls of Serra da Capivara are the colour of dried blood, and the rock paintings on them have been here for longer than the pyramids of Egypt. You walk through corridors of caatinga scrub in blistering heat, then duck into a rock shelter and find yourself face to face with red ochre figures — hunters, dancers, animals — painted by people whose existence rewrites the timeline of human presence in the Americas.

Serra da Capivara National Park in Piauí is a UNESCO World Heritage Site containing over thirty thousand individual rock paintings across more than six hundred archaeological sites — more prehistoric art than anywhere else in the Americas. Some paintings are estimated at twenty-five thousand years old, predating the widely accepted date of human arrival in the Western Hemisphere. The park sits in the semi-arid caatinga biome, where thorny scrub erupts into vivid green after rare rains. The nearest town, São Raimundo Nonato, is several hours from any major airport, and the park receives fewer than fifteen thousand visitors per year — a fraction of what comparable sites elsewhere attract.
