Iguazu Falls

Iguazu Falls, Argentina and Brazil

Eleanor Roosevelt, on seeing Iguazu for the first time, reportedly said “Poor Niagara.” The comparison is accurate. At peak flow in March and April, around 12,750 cubic metres per second pass over a horseshoe-shaped cliff 2.7 kilometres wide. Niagara’s flow at peak is about 5,700 cubic metres per second across a much narrower crest. Iguazu is also wider than Victoria Falls. The superlatives are legitimate.

The falls are split between Argentina and Brazil by the Iguazu River. Each side is a separate national park requiring a separate entry fee and a border crossing. The standard advice – visit both sides over two days – is correct.

Argentine Side

The Argentine side (Parque Nacional Iguazú) takes the better part of a full day. Entry costs around ARS 10,000 (subject to Argentina’s ongoing inflation, verify before you go). A narrow-gauge train runs through the park to three walking circuits: Upper Trail, Lower Trail, and the Garganta del Diablo platform.

The Lower Trail is the most immersive – you walk at base level close to individual falls and get soaked. The Garganta del Diablo (Devil’s Throat) is the main event: a horseshoe wall of water 80 metres high, approached by a metal catwalk across the river. The platform is close enough that visibility is near zero due to spray. The Upper Trail gives the panoramic overview.

Boat tours by Iguazu Jungle (around $25-35) go directly under the lower falls. You will get completely wet. Waterproof your camera and phone before boarding; there is no version of this that involves staying dry.

Brazilian Side

The Brazilian side (Parque Nacional do Iguaçu) entry is around R$90. The main walkway is a single panoramic path along the cliff edge giving an unobstructed frontal view of the entire Argentine side – this is the view in most photographs. The perspective is broader and more cinematic than the Argentine experience, but less intimate.

The Brazilian side can be covered in 2-3 hours. Come in the morning when the light is directly on the falls.

Logistics

The nearest city is Foz do Iguaçu (Brazil), which has the most accommodation and is better connected by air (IGU airport). Puerto Iguazú (Argentina) is smaller, directly across the border, and has better access to the Argentine park. Border crossings between the two are straightforward with a passport.

The Belmond Hotel das Cataratas, inside the Brazilian park, allows access to the falls before and after visitor hours when crowds are absent. The price (from around $500/night) reflects that privilege. For most visitors, staying in Foz do Iguaçu and taking the 20-minute bus to the park is the practical approach.

Wildlife

Coatis – raccoon-sized omnivores with pointed snouts – are aggressive at the food areas and will take anything edible. Do not feed them and keep bags closed; they are persistent. Toucans, parrots, and large blue Morpho butterflies are common throughout both parks. Caimans are occasionally seen along the lower Iguazu river.

When to Go

Peak flow in March-April after the rainy season is the most dramatic time. Low flow in August-September makes the Devil’s Throat less overwhelming but visibility through spray is better. July-August is cooler (15-20°C) and school holiday period in Brazil – book accommodation well ahead.
