With clear skies and comfortable weather, June is an excellent time to visit Iguazú. Hike along the waterfalls' edge on a series of catwalks, raft on the river, or trek along quiet forest paths, spotting butterflies and capuchin monkeys in the wild: with relatively few crowds visiting, you'll enjoy peace and quiet in the parks. Learn more about what to expect with this monthly guide.


Mid- to late-June marks the start of the transition from autumn to winter in the region of northern Argentina and southern Brazil, where Iguazú Falls are located.

This is one of the most comfortable times of the year to visit the area: unlike in summer, when temperatures soar into the high 90s and humidity peaks, the region sees highs in the mid-70s in June, with lows dipping into the upper 50s at night. Bring a jacket and sunscreen, but don't worry too much about rainy days: this is one of the region's drier months

Crowds & Costs

In terms of both crowds and prices, June is a good time to visit Iguazú. The region sees fewer domestic and international visitors than at many other times of the year: it's the middle of the school year in Argentina and Brazil, so fewer families make trips, while travelers from the northern hemisphere, who typically flock to Brazil and Argentina during winter in their own countries, make different travel plans as the seasons change. 

Particularly if you visit during the week, you'll see smaller crowds than usual in the national parks. It's still smart fo reserve ahead of time if you're intent on staying at a particular hotel—or if you want to rent a car, as local outfitters sometimes run low on vehicles during busy weekends.

June is also a good time of year to take advantage of off-season promotions and promotional rates at hotels like the Gran Meliá Iguazú, located inside Iguazú National Park, which is often filled to capacity during busy summer months.

What To Do

Hike (and ride the train partway) to Garganta del Diablo (Devil's Throat), the lookout point over one of the waterfalls' most dramatic sections, first thing in the morning. Or go late in the afternoon when the lighting is ideal for photos. Go on a boat ride, choosing between the exhilarating Gran Aventura trip, which takes you close to the base of the falls on a speedboat (you'll get wet, so make sure it's a warm day) and the calmer Ecological Trip, a rafting excursion that leaves from the Garganta del Diablo train station. You can find out more about both options at the park's Visitors Center.

Keep your eyes open for wildlife, from capuchin monkeys to tropical birds and butterflies, as you walk along the parks' trails and catwalks. To get away from people altogether, consider the Macuco Trail, which takes you off the beaten path and deep into the forest. Bring a picnic and plenty of water—and mosquito repellant. Visit key attractions in the park, like picturesque Bossetti Jump, late in the day for the best photo ops unobstructed by people. Though the falls are usually a little less dramatic at this time of year, due to the low level of the river, June is a good time to take photos.

What To Look For

All kinds of wildlife are active in the parks at this time of year. Look up and around on the hiking trail to see some of the region's more than 430 species of birds—including three kinds of toucans and a variety of brightly colored hummingbirds—and more than 70 species of mammals. In winter, large lizards often crawl out of their hiding places in search of sunshine.

Monkeys tend to congregate where humans leave food behind, especially in the parks' concession areas, but it's also possible to spot thems swinging through the trees in the jungle as you hike. Beware of raccoon-like coatis: they'll try to take a sandwich right out of your hand if given the chance.

Events & Activities

Walks in the Moonlight: Iguazú National Park offers guided nocturnal tours on five evenings each month. The schedule depends on the lunar calendar.
