Cheapest months to fly to Iguazu
IGR runs on a pretty predictable rhythm. Fares from Buenos Aires stay reasonable through most of the year, then spike hard in July when Argentine school holidays hit and again in late December through January when half the country decides they need to see waterfalls. The wet season (November through March) actually produces some of the most dramatic water flow, but it also brings humidity that'll flatten you. The sweet spot most years is April through early June — crowds thin out, the park is still lush, and airlines haven't caught on enough to gouge you for it. Yet.
Why visit Iguazu?
Iguazu Falls is, without exaggeration, the kind of place that makes Niagara look like a decorative fountain. The Argentine side gives you the Devil's Throat walkway, where you stand directly over the main cascade and get soaked whether you want to or not. Beyond the falls, the surrounding national park is genuinely worth your time — coatis will steal your lunch, toucans are an actual bird you'll see without trying, and the trails get into serious jungle. Iguazu town itself is small and functional rather than charming, but the food scene has improved, with regional dishes leaning on local river fish and Misionero herbs that you won't find replicated in Buenos Aires restaurants trying to approximate them.

Tips for getting a cheap fare to Iguazu
Book Buenos Aires to IGR early — that route fills up because Argentines travel it constantly for long weekends, not just tourists. I'd watch fares in May for travel in late June, just before the July holiday crunch. Rosario (ROS) occasionally offers competitive connections if you're already in that part of the country. For currency, Argentina's exchange situation has been complicated for years, so check current conditions before you go — the official rate and your actual purchasing power can diverge significantly. Most nationalities get 90 days on arrival, no visa required, but confirm your specific passport situation before booking anything.
