We made this crossing at Iguassu Falls, and I haven’t included photos owing to the sensitive nature of border stations (though this one seems exceptionally relaxed).
We caught the bus directly from the National Park on the Brazilian side and went to Puerto Iguazu. The bus line was Rio Uruguay and the cost was 10 reals or 50 pesos.
We made sure to hand the driver our passports and Brazil departure cards (VITAL) which was handled for us without us even having to go to the window ourselves.
Argentinian immigration was a breeze and essentially a formality.
We drove on into Puerto Iguazu without incident and out driver was even good enough to stop at the side of the road when we spotted our hotel.
Puerto Iguazu is really small, and walking anywhere from the sole bus station is really easy with a map.
So, here we go, viva Argentina!
