I should make a comment about breakfast in Brazil. It's not your run of the mill cereal & toast type of set up. Normally you can get those, but there is also a big spread of tropical fruits & cakes. Yes cake for breakfast . It's what they do over there. It's a bit of a sugar rush early in the morning & a shock to the system until you get used to it.
After breakfast we were back in the van & off to Argentina to see the other side of the falls. The border crossing into Argentina was a bit of a drag & we had to let our passports go with the driver. It was all fine, but it was just boring sitting in the bus.
We were eventually on our way again & quickly reached the national park that surrounds the falls.
