Only very recently opened to the public, Serra das Confusoes was a hiding place for natives pushed from their homes by invading Portuguese as late as the mid-20th century and has long been seen as largely inaccessible by the majority of tourists. Home to a number of endangered species, including jaguar and howler monkey, the park gets its name for the changing colors of its rock during different times of day, "confusing" the onlooker. The hikes here can be magnificent, with a proliferation of tall, rounded rock formations throughout the park to please the eye. There are also a number of caves and rock art, although the most popular is Riacho dos Bois. Because this and other parks in the Piaui region are so far from Brazilian hubs like Recife or Fortaleza, our suggestion is to book with a tour guide ahead of time and try to fly in, otherwise be prepared to spend a full day traveling with the very real possibility that you may get lost in one of the poorer, more dangerous areas of the country.
Note:The park office is in the nearby town of Caracol. Stop here to find a guide if need be; if you don't speak Portuguese well, make sure that you know what landmarks you are looking to see beforehand.
