It’s about a 2 hour drive from Brasilia, in order to get to the waterfall, but it is definitely worth the trek![as described by Giddyforpoints, on First2Board – thank you for sharing!
Location: Formosa, Brazil
The Itiquira Falls is a waterfall in Brazil. They are located 34 kilometers north of Formosa in the state of Goiás and 115 kilometers from Brasília on a paved road. The falls have a height of 168 meters, making them possibly the highest accessible waterfall in Brazil and the second highest overall. The falls are formed by the drop of the Itiquira River from the higher central plateau north of Formosa into the deep Paraná River valley. The waters are unpolluted and a bottling plant is located on the river above the falls. The area is a municipal park and is protected from development. There are tourist facilities outside the park, near the entrance. (source: Wikipedia)
