Sete Cidades National Park

Sete Cidades National Park is a protected area in the state of Piauí in northeastern Brazil, noted for its unusual sandstone rock formations and archaeological sites. The park preserves both natural landscape features and evidence of prehistoric human activity.

Visitors explore trails that pass among sandstone pillars, natural arches and grouped rock formations that have been carved by erosion into shapes locally named after towns or features. The park also contains rock paintings and archaeological sites that attract researchers and visitors interested in prehistory and geology. Facilities are basic and visits are typically day-trips from nearby towns.

The area has been recognized for its geological and archaeological importance and brought under protective status to conserve rock formations and prehistoric sites. Research and conservation measures aim to manage visitor impacts on sensitive features.

The park lies in northern Piauí, Brazil, in a semi-arid interior landscape; the nearest local towns provide access for day visits and regional roads connect the area to larger urban centres in the state.
