Jalapão is a state park in eastern Tocantins, Brazil, about 250 kilometres (160 mi) from the Tocantins capital, Palmas. It occupies 34,000 square kilometres (13,000 sq mi), making it the largest state park in Tocantins. The region is considered one of the biggest attractions of the cerrado, a tropical savanna ecoregion of Brazil, and has increasingly received interest among adventure tourism and ecotourism fans. The vegetation is predominantly savannas, cut off by a web of rivers, streams and creeks.
Found in full transitional forest, Jalapão is dominated by scrubland vegetation similar to the savannas, where waterfalls, rivers with crystal clear waters, rapids and large plateaus make the landscape. It is in this scenario where golden sand dunes, up to 30 metres (98 ft) high, stand out, giving the place its name: desert of Jalapão. It would be a desert, if Jalapão were not also a paradise of waters, flowers, and exotic animals.
