Viewing the Brazilian side of Cataratas do Iguacu
On a visit to Cataratas do Iguacu in Brazil the experience centres on a sequence of vantage points that show the falls from different angles, with the river, forest and escarpment all in view.Visitor infrastructure in the park A main access road inside Iguaçu National Park runs towards the river, and park transport carries visitors through forest to viewing areas where walkways extend towards the edge of the gorge.
From these viewpoints the line of waterfalls appears as a broken arc, with sections of falling water interspersed with cliffs and islands covered in vegetation.Arc of waterfalls across the escarpment The combination of the wide river, the height of the escarpment and the number of separate cataracts makes Cataratas do Iguacu a layered landscape rather than a single drop, and the Brazilian side provides an overview of this broken river front from above and beside the gorge.Series of cataracts on the river
