Iguazu Falls is, without question, one of the most awe-inspiring natural spectacles on Earth. Straddling the border between Argentina and Brazil, within the lush Atlantic Forest, these waterfalls were declared a UNESCO World Heritage Site in 1984 and voted one of the New Seven Wonders of Nature in 2011. With 275 individual cascades spanning nearly 3 kilometers and a maximum drop of 80 meters at the legendary Devil's Throat (Garganta del Diablo), Iguazu is wider than Niagara and taller than Victoria Falls.
Each year, over 1.5 million visitors make their way to Puerto Iguazu (Argentina) and Foz do Iguacu (Brazil) to witness this natural wonder. And rightly so: the combination of the thundering roar of water, the mist that soaks everything around it, the rainbows that appear with every ray of sunlight, and the subtropical jungle teeming with toucans, coatis, and butterflies creates a multisensory experience you will never forget.

Argentine Side vs Brazilian Side
The Argentine side immerses you within the falls: walkways take you over and between the cascades, and you stand at the edge of the Devil's Throat looking straight down into the abyss. The Brazilian side gives you the iconic panoramic photo with the entire 2.7 km front of falls unfolding before your eyes. If you can only pick one, go Argentine. If you have two days (recommended), do both.

The best times are March-June (autumn) and August-November (spring). Water volume is most impressive after summer rains (January-March), but the heat can be overwhelming. Winter (June-August) offers fewer crowds and pleasant temperatures of 15-22°C.
Should I visit the Argentine or Brazilian side?
Both! They offer completely different experiences. The Argentine side immerses you within the falls with walkways over the cascades. The Brazilian side offers the iconic panoramic view. Ideally, dedicate one full day to each side.

Minimum 2 days (one for each side). With 3-4 days you can add the jungle, Bird Park, Jesuit ruins of San Ignacio, and Wanda mines. Five days allows for the Moconá Falls excursion too.
