Best time to visit the Iguaçu Falls with children
For families, safety and comfort are priorities. The months of April, May, and August offer milder temperatures and less rain, reducing risks of slippery walkways.
At this time, there are also fewer crowds in the parks, making circulation with strollers easier and avoiding long lines. In addition, hotels usually offer more affordable rates.
Best time to visit without lines
High season concentrates most visitors and increases waiting times in lines. To avoid this, it is important to consider months of less movement.
The most recommended periods are May, June, and August, when there are no school vacations or long holidays. In these months, waiting time for tickets and internal transportation is significantly reduced.
Best time for photos at the Iguaçu Falls
Photography is one of the great attractions of the visit. To capture clearer and sharper images, the ideal is to travel in autumn and winter, when the water volume is lower and the spray dissipates.
Sunny mornings increase the chances of seeing rainbows formed over the Devil’s Throat, a unique setting for photographers.
Practical tip: use a raincoat and camera protection even in the driest periods, as proximity to the falls always generates splashes.
What is high season at the Iguaçu Falls?
High season happens mainly in three periods:
- July: school holidays in Brazil.
- December and January: summer holidays, with a large flow of national and international visitors.
- Long holidays: Carnival, Easter, and national holidays.
On these dates, hotels have higher prices and visitation is intense. For those seeking tranquility, it is advisable to avoid these times.
Best time to visit the Argentine side of the Falls
The Argentine side has more trails, requiring more walking time. Therefore, the drier months, such as April to September, are the most recommended.
During this period, the walkways are less slippery, increasing safety. It is worth reserving at least a full day to explore this area calmly.
Best time for extra tours in Foz do Iguaçu
In addition to the Falls, Foz do Iguaçu offers attractions such as the Bird Park, the Itaipu Dam, and the Three Borders Landmark. These tours can be done at any time, but some conditions favor the experience.

Step by step to choose the time of your trip
Defining the best time to visit the Iguaçu Falls requires planning. The decision should consider climate, water volume, tourist movement, and traveler profile.
To make it easier, follow this step by step:
- Identify your priority: if you want to see the falls at their peak, choose the rainy months. If you prefer more visible falls and sharp photos, opt for the dry period.
- Analyze the region’s climate: decide if you prefer intense heat with summer rains or milder temperatures in autumn and winter.
- Consider your travel profile: families with children and seniors usually feel more comfortable in stable climates and less wet trails.
