Sete Cidades National Park, National park in Brasileira, Brazil

Sete Cidades National Park covers 7,700 hectares split between Brasileira (26.21%) and Piracuruca (73.77%) in Piauí. Its main draw is a geological formation of red sandstone outcrops, with some prehistoric cave paintings and inscriptions. The park also holds arid savanna with babassu forest and contact zones between savanna, arid savanna and seasonal forest.

Sete Cidades National Park was created by decree 50.744 on 8 June 1961, signed by President Jânio Quadros. A management plan was published on 31 December 1978 but never officially formalized. Ordnance 126 of 14 December 2010 established the park's consultative council.

The name "Sete Cidades" (Seven Cities) comes from the seven groups of sandstone formations that early travellers took for ruined cities. The park also holds prehistoric cave paintings and inscriptions, which visitors can see on guided walks. The formations and the rock art are the park's main attractions.

Visitors should hire a local guide to explore the different areas safely and understand the rock art properly. Access is arranged through a visitor center at the entrance where all necessary information is provided.

Several rock formations have naturally eroded into shapes that resemble familiar objects, such as an elephant or a turtle. These accidental resemblances often serve visitors as landmarks when exploring the parkland.
