Salto Sao Francisco waterfall, Waterfall in Paraná, Brazil

Salto São Francisco is a free-falling waterfall of about 196 metres on the Serra da Esperança, at the triple border of Guarapuava, Prudentópolis and Turvo in Paraná. The water turns to mist before reaching the ground, a drop compared to a 60-storey building. The cliff belongs to the Serra Geral Formation, basaltic flows of the Paraná Basin dated to 137–127 million years ago.

The waterfall lies on the Serra da Esperança, the eastern edge of Paraná's Third Plateau, a basalt plateau formed by lava flows in the Paraná Basin between 137 and 127 million years ago, part of the Serra Geral Formation. The state park and the Serra da Esperança environmental protection area now cover the falls, and the Guarapuava municipal government later created the Parque Municipal São Francisco da Esperança with walking trails and a panoramic viewpoint.

The falls sit where the municipalities of Guarapuava, Prudentópolis and Turvo meet, and the surrounding Serra da Esperança marks the eastern edge of Paraná's Third Plateau, also called the Guarapuava plateau. That plateau is built from basaltic lava flows of the Serra Geral Formation, erupted in the Paraná Basin between 137 and 127 million years ago. The municipal park on the Guarapuava side, São Francisco da Esperança, has walking trails and a panoramic viewpoint over the drop.

The waterfall lies in the Serra da Esperança, on the triple border of Guarapuava, Prudentópolis and Turvo, inside the Salto São Francisco da Esperança state park and the Serra da Esperança environmental protection area. The municipal park created by Guarapuava has walking trails and a panoramic viewpoint over the drop. The water turns to mist before reaching the ground, so the base is often wet.
