Sete Cidades
Rock formations so orderly that scientists once debated whether a lost civilisation built them.
The sandstone formations stand in rows so regular they look designed — columns, arches, and flat-topped towers arranged across the cerrado as if someone laid them out with a ruler. Sete Cidades in Piauí is seven clusters of rock formations so orderly that a 1970s researcher proposed they were Phoenician inscriptions. The theory was debunked, but no one has fully explained why the shapes are so precise. The silence between them is immense.
Sete Cidades National Park protects a landscape of eroded sandstone formations spread across roughly sixty square kilometres of cerrado in northern Piauí. The seven clusters — numbered Primeira Cidade through Sétima Cidade — were mapped by the first scientists to survey the site and named for their resemblance to ruined urban structures. The park receives fewer than twenty thousand visitors annually, and trails between the formations have minimal signage, giving exploration a genuinely unscripted feel. Armadillos and howler monkeys are commonly spotted, and the cerrado vegetation has never been cleared. Rock paintings within the formations date human presence here to thousands of years before any European arrival.
Solo
Under twenty thousand visitors a year means you will likely walk the trails alone. The silence, the mystery of the formations, and the sparse cerrado landscape reward slow, contemplative exploration.
Couple
Wandering between the seven stone cities together, debating whether the shapes are natural or not, spotting armadillos on the trail — Sete Cidades is a place for couples who prefer discovery to resort.
- Seven separate clusters of formations dot the landscape — each cluster was named (Primeira Cidade, Segunda Cidade) by the first scientists who mapped them.
- A 1970s researcher proposed the formations were Phoenician inscriptions — the theory was debunked, but no agreed explanation for the regularity of the shapes exists.
- The park receives under twenty thousand visitors annually — the trails have almost no signage and wandering between the formations feels genuinely exploratory.
- Armadillos and howler monkeys are commonly seen on the trails — the cerrado here has never been cleared.
Cajuína — the golden filtered cashew drink sacred to Piauí — served ice cold in recycled bottles.

A binational cloud forest so dense and remote that vast sections remain unmapped.
