Iguazu Falls Border Crossings in Brazil: real experience from chats
Short answer
One-way international car rentals between Brazil and Argentina are rarely available, so travelers should rely on flights or long-distance 'Cama' sleeper buses. For cross-border transit at Iguazu, hiring local taxi drivers or using multi-leg bus routes is more reliable than ridesharing apps, and you must complete passport control in both directions.
From real experience
One-way international car rentals between Brazil and Argentina are practically non-existent or prohibitively expensive.
To travel from Brazil (e.g., Rio) to Argentina (e.g., Buenos Aires) via Iguazu Falls, travelers should fly to Foz do Iguaçu or take long-distance sleeper buses (class 'Cama' with fully reclining seats). For crossing the border at Iguazu, hiring a local taxi driver who coordinates with an Argentinian counterpart is highly recommended for hassle-free transit.

There is no direct public bus service from the Argentine Falls national park (Cataratas Argentina) directly to Foz do Iguaçu (Brazil).
Travelers must take a bus to the Puerto Iguazú bus terminal first, and transfer to a bus heading to Brazil. Ridesharing apps like Uber do not operate reliably across the Argentina-Brazil border from the park, making pre-booked transfers or multi-leg bus travel the primary transit options.

Roads leading to the airport and Iguazu National Park on the Brazilian side are undergoing maintenance, with a lane closure causing significant traffic delays.
Travelers are advised to allocate extra time for their journey and depart earlier. While some report minimal delays due to the construction of an interchange, others describe complete standstill traffic. This situation has been ongoing for about two years.

For trips to Iguaçu Falls from Rio de Janeiro, independent planning is typically more cost-effective than pre-booked commercial tours.
Transport options include flights to the local airport, followed by bus or taxi transfers to the falls area. Tours found on Russian-language booking sites are often overpriced.
