Humid, social, and slightly transient, this is an early-start town of bus plans, drying shoes, terrace beers, and quick friendships before everyone moves on.

Mist hangs in the air before the water comes into view. Puerto Iguazú feels like a small jungle-edge base camp, with buses, daypacks, and sleepy breakfast tables all pointed toward the falls. You ride out past thick green forest, walk the park’s raised trails, and end up at Garganta del Diablo with spray on your face and that low constant roar in your chest. Back in town, the Triple Frontier setting keeps everything slightly in motion. Puerto Iguazú suits you if a trip needs one huge natural hit and very little fluff.

Humid, social, and slightly transient, this is an early-start town of bus plans, drying shoes, terrace beers, and quick friendships before everyone moves on.
Give it 2 to 3 nights, enough for the falls, a flexible weather buffer, and one relaxed evening back in town.
Skip it if one big sight is never enough, or if border crossings, park extras, and a touristy little town sound irritating.
Half the transport story here involves another country. Plenty of backpackers come through Foz do Iguaçu in Brazil and cross by Rio Uruguay bus, which runs roughly every 30 to 60 minutes and usually costs around ARS 7,000 to 10,000 depending on the route. You may need to get off for both immigration posts, and if your bus leaves, the next one is usually not far behind. Flying from Buenos Aires to IGR is the easy play, about 2 hours, then around 30 minutes into town by bus or taxi. Same-day booking is usually fine for local buses, less so for flights.
April, May, and early June are the sweet spot for most people. You still get warm weather, usually around 22°C to 26°C, but the air is less punishing than high summer and walking the circuits feels easier. Late November and early December can be excellent too, though rain can still wipe out a few days. January and February are hot, wet, and sticky, often above 30°C. July is cooler and pleasant, but busier. The park stays open year-round, though heavy rain can suspend boat trips or affect some circuits.
Cash saves headaches here. Cards work in plenty of places, and the Rio Uruguay counter at the bus terminal often takes them, but small shops, tips, and random border-day purchases still go smoother in pesos. ATMs exist, just do not trust them as your only plan because fees and empty machines happen. Internet in town is decent, Wi-Fi is usually fine, and signal inside the park gets patchy. Bring snacks for the falls because food inside is acceptable but overpriced. Also, short power cuts do happen.
The main risk here is small, annoying crime, not anything dramatic. After dark, stay sharper than in a lot of Argentina, especially around the Triple Frontier area and quieter streets near the border. Keep your phone away when waiting around, split your cash, and zip your daypack fully. Registered taxis are the sensible call at night. The land crossing to Brazil is generally easy and safe, but daytime is better. At night, transport options thin out, and long waits in the heat are no fun either.
