The Prehistoric Paintings of Serra da Capivara
Serra da Capivara National Park boasts the largest collection of prehistoric paintings in the Americas that may also be the oldest. There is a fierce debate brewing in the archeology world about whether or not these secluded rock shelters in the Brazilian interior house America's oldest art — they have been estimated to be both as old as 36,000 years old and closer to 25,000. Either way, this collection of paintings depicting early humans and wild animals dancing, fighting, hunting, and having sex is impressive — as is the hike to see them through the unique Brazilian biome known as Caatinga. This semi-arid park is worth the trip just for the nature alone, from the towering canyon walls to the sprawling savannah rife with wildlife.
What you need to know: Certified guides are required to explore the national park. You can hire one in São Raimundo Nonato, the closet city to the entrance. Four daily buses travel between São Raimundo Nonato and the state capital of Teresina, which has air connections throughout Brazil.
