The buses are very comfortable, we bought seats reclinable up to 180º and dinner is offered. The one down side is that the A/C is set to freezing temperatures!! We have seen this everywhere in Argentina, maybe the drivers are very hot ? (pun intended!)
When we got to Iguazu, it was so hot (40 º !!) and humid!! Sweat wouldn't stop pouring from our bodies!
Some littles boats were seen travelling the river (Parana River meets the Iguazu river on this point), smugglers maybe?
The next day we finally visited the Iguazu Falls, we were all ready for hiking! Sun protector, mosquito protection, good boots - go!
When we got there, the whole trail is paved! It is ready for all kinds of ages and therefore was more a walk in a park than a hiking trip as we thought!
The temperature in the Park was much nicer, due to all the trees and the Falls, finally we stopped sweating! We wanted to stay there forever! The Falls is an amazing show of nature power, you just couldn't stop staring at it!!
It is also full of butterflies who are used to the human presence and interact with you! Also some coatis interact with the visitors, but these just want your food!
