Devil's Throat
Take the train and walkway to the edge of the largest fall.
{{item.title}}
In short
On the border of Argentina and Brazil, the Iguazu Falls are a chain of about 275 waterfalls nearly 2.7 km wide, protected by national parks on both sides. From June 2026 foreigners pay 60,000 pesos on the Argentine side, and Brazil charges separately in reais. The Argentine side takes five to seven hours, starting with the first train to the Devil's Throat.
The Iguazu Falls lie on the Iguazu River on the border between the province of Misiones in Argentina and the state of Parana in Brazil, close to where both countries meet Paraguay. Argentina created Iguazu National Park in 1934 and Brazil created Iguacu National Park in 1939. UNESCO listed the Argentine park in 1984 and the Brazilian park in 1986.
The name comes from the Guarani words for big water. The first European known to have seen the falls was the Spanish explorer Alvar Nunez Cabeza de Vaca in 1541. The towns of Puerto Iguazu in Argentina and Foz do Iguacu in Brazil serve as bases for visitors.
The falls stretch for about 2.7 kilometres and are made up of around 275 separate drops, depending on the water level. The largest is the Devil's Throat, a U shaped chasm about 80 metres high where roughly half of the river's flow pours in. Most of the falls are on the Argentine side, while the Brazilian side gives the widest panoramic view.
On the Argentine side, a small train carries visitors through the forest to the Devil's Throat walkway and to the Upper and Lower circuits, which pass close to and above the falls. On the Brazilian side, a single trail runs along the canyon to a walkway that reaches into the spray. Boat trips run close to the base of the falls. The surrounding subtropical Atlantic Forest is home to coatis, toucans, many butterflies and the rarely seen jaguar.
Each park charges its own entry fee, with higher rates for foreign visitors, and tickets can be bought online or at the gate. Visiting both sides takes at least two days. Water flow is highest from December to March, and the drier months give clearer views.
