Foz da Iguazú to Puerto Iguazú (Brazil to Argentina)

Our gateway to Argentina came via a 20 minute local bus ride to the Brazilian border to clear immigration. It was kinda cool leaving a country and entering another via a land border, I can’t remember the last time we did this, perhaps Laos/Thailand a few years back.
We paid our $R4 and jumped on the bus full of locals (whether they were Argentineans or Brazilians I am unsure) and about eight of us tourist type looking people, and off we went to the Brazil border, where us eight hoped off and the bus drove off. This was expected and all we needed to do was get a stamp in our passport and return to the same bus stop 20 meters away to await the next bus that we would hop on to take us to the next border, no need to pay again.
We waited about half an hour for it to show up and then once again we were off for another 10 minutes down the road to Argentinean immigration. Off we hopped and it was once again the touristy looking types lining up for a stamp. This time the stamping process looked a little more professional and we even had to put our luggage through a x-ray machine (although no one was actually watching the screen as the items passed through). Even better Kiwi’s are granted an automatic visa, no fee’s required – where as similar countries Australia, Canada, UK etc. will all need to hand over between $100-$150US
The bus waited for us this time, the driver had collected up our little tickets we received on the first bus – I’m assuming to keep count of how many touristy looking people he would need to bundle back on to the bus, post stamp. We were on our way again and were at the main bus station of Puerto Igazcu after half an hour.
Easy Peasy, and now a whole new country to explore.
