Iguazú Falls

Iguazú Falls consists of around 275 individual waterfalls spread across nearly 3 kilometers on the border between Argentina and Brazil, a scale that genuinely dwarfs Niagara Falls in width and rivals Victoria Falls in height — a combination that reportedly led Eleanor Roosevelt to exclaim "Poor Niagara" on her first visit, a line locals still repeat with evident pride.

The Argentina side offers the more immersive experience, with metal walkways built directly over and alongside the falls, including a path leading straight to the edge of the Devil's Throat (Garganta del Diablo), the most powerful single section, where the sheer volume and noise of falling water make conversation genuinely difficult at close range.

The Brazil side, by contrast, sits across the canyon and gives a more sweeping, photographable panoramic view of the entire falls system at once — the two national parks, one on each side of the border, are widely considered complementary rather than redundant, and visitors with time for both usually come away glad they made the crossing.

Beyond the falls themselves, the surrounding national park protects a substantial stretch of Atlantic Forest, one of the most biodiverse and endangered rainforest ecosystems on Earth, and genuine wildlife encounters are common along the walkways — coatis (a raccoon-like animal notorious for stealing unattended food), toucans, and capybaras all regularly appear without requiring a dedicated safari.

Boat tours that motor directly into the spray beneath several of the falls give a completely different, far more visceral experience than the walkways — a genuinely soaking, adrenaline-charged few minutes that most visitors describe as a highlight, provided electronics are properly protected beforehand.
