Iguazú Falls can be visited from both sides of the border: on the Argentine side, in Iguazú National Park, you walk on walkways above and at the foot of the falls as far as the Garganta del Diablo (Devil’s Throat); on the Brazilian side, you get the overview. This guide mostly covers the Argentine side, from Puerto Iguazú: official tickets, opening hours, circuits and the best season according to the Argentine weather service’s normals.
It complements our Argentina travel guide, which recommends at least two days on site. What is specific to this page: a rain / heat / daylight table by month, and a decision guide to choose your plan between the two sides.

Best time to visit Iguazú
The park is open even in the rain, and the flow of the falls depends on rainfall in the river basin. The normals from the Servicio Meteorológico Nacional for Puerto Iguazú, repeated on our page on the best time to visit Argentina, show rain all year (84 to 247 mm / 3.3 to 9.7 in a month) and strong heat from October to March. We add sunrise and sunset times, useful for arriving at opening time.

How to read it: from April to September, maximum temperatures stay below 28 °C (82 °F); October and December are the wettest months. The park does not publish monthly visitor-number figures, so we give none. The sun rises before opening time all year: arriving at 8 am lets you take the first train to the Garganta.
Argentine or Brazilian side?
- Just one day: the Argentine side (walkways, Garganta del Diablo), which takes the most time.
- Two days: Argentine on the first day, Brazilian (panoramic view) on the second, or a second Argentine day at 50% off.
- Reduced mobility: the Garganta and Superior circuits are listed as 100% wheelchair accessible on the Argentine side.
- Crossing into Brazil: this is an international border: see entry requirements for Brazil in our Brazil travel guide.
Suggested route
- Arrive at opening time, take the first train to the Garganta station.
- Garganta del Diablo (walkway above the gorge).
- Train back to Cataratas station: Circuito Superior (90 min).
- Circuito Inferior (90 min), at the foot of the falls.
- Sendero Verde to walk back to the central station if time allows.
Getting there
The base town on the Argentine side is Puerto Iguazú, linked to Buenos Aires by air (see our Argentina guide). From the park’s central station, the Sendero Verde (15 minutes on foot) leads to Cataratas station; the train then serves the Garganta.

- Water, low-impact sunscreen and repellent, light clothing, walking shoes, a cap and a rain jacket: official advice.
- The park lists accessible circuits and walkways; the Garganta and the Circuito Superior are 100% wheelchair accessible.
Common mistakes

- Throwing away the first day’s ticket: it gives you 50% off the next day.
- Planning to pay in dollars or euros: the ticket office accepts cards and Argentine pesos.
- Buying for the wrong date: no changes are possible.
