Iguazu Falls
Iguazu Falls is a 1.7-mile arc of roughly 275 individual waterfalls straddling the Argentina-Brazil border, and genuinely dwarfs Niagara in both width and drama. The Argentine side (entry about $22) puts you on walkways directly over and between the falls, including the thundering Devil's Throat; the Brazilian side gives the better panoramic overview shot. It's a direct 2-hour flight from Buenos Aires to Puerto Iguazú, and worth a full day, ideally two if you're doing both country sides.
Niagara Falls is one waterfall. Iguazu is roughly 275 of them, spread across a mile and a half of jungle, and the first time you round a bend on the walkway and the Devil's Throat comes into view — a horseshoe of cascading water you can feel as mist from a hundred yards away — most visitors stop talking for a minute.
Argentina side or Brazil side?
| Argentina side | Brazil side | |
|---|---|---|
| Best for | Up-close, immersive walkways between and above the falls | The big panoramic overview shot of the whole system |
| Time needed | Full day | Half day (2–3 hours) |
| Devil's Throat access | Yes, via a dedicated train and walkway | A more distant viewpoint |
| Entry (foreigners) | ~$22 | ~$20 (Brazilian reais) |
If you have two days, do both sides — most visitors say the Argentina side is the more memorable of the two, but the Brazil side's overview genuinely adds context you don't get up close. Crossing requires your passport, and depending on your nationality, a Brazilian visa or eVisa arranged in advance — check that separately, since not every nationality that's visa-free for Argentina is visa-free for Brazil.
What to see on the Argentine side
- The Devil's Throat (Garganta del Diablo) — the single most powerful section, reached by a short eco-train ride and a walkway that puts you directly above the thundering horseshoe drop.
- The Upper and Lower Circuits — two separate walking trails offering different angles on dozens of individual falls, from above and from water level.
- A boat trip under the falls — an optional, genuinely soaking add-on (bring a dry bag) that takes you right up to the base of some of the smaller falls.
Getting there
Puerto Iguazú has its own airport with direct flights from Buenos Aires (about 2 hours) — by far the easiest way in. An overland bus from Buenos Aires takes 16–18 hours; only worth it for travelers already road-tripping through the north.
When to visit
The falls are impressive year-round, but flow is heaviest after the rainy season (roughly November–March), which is also the hottest and most humid time to visit. Shoulder months (April–May, September–October) offer a more comfortable climate with still-strong water flow.
Where to stay — Puerto Iguazú
Puerto Iguazú, the small town on the Argentine side, is the practical base for most visitors — a range of hotels from budget guesthouses to a couple of higher-end resorts, a 15–20 minute drive or bus ride from the park entrance. There's little reason to stay elsewhere unless you're specifically basing on the Brazilian or Paraguayan side of the tri-border area.
What to pack
- A poncho or quick-dry layer if you're doing the boat trip under the falls — you will get properly soaked, not just misted.
- Insect repellent — the surrounding jungle is humid and mosquitoes are a real presence, especially at dawn and dusk.
- A dry bag or waterproof phone case for cameras and electronics near the walkways and boat.
