The city of Iguazú
A good reccomendation would be to leave the falls for last, as they're so breath-taking that nothing else will seem as beautiful as they really are.
Puerto Iguazú is an awe-inspiring place. Located in the triple border of South America, this place offers loads of beautiful settings and a mix of fauna and flora it's difficult to find anywhere else.
The city buildings are no taller than a one story house, creating an atmosphere of a quite place and always giving you a very relaxing view of its clear skies.
Also, it makes it easier to see when there might be a storm coming.
Two Reasons To Take a Pair of Sandals With You
If you ever get caught by rain, do not disspair as tropical rain is not cold at all and not even the temperature goes down.
Beware that the streets get incredibly flooded so if you get caught in the middle of a storm you can either wait untill it stops (wich is not really reccomended as tropical storms can last quite long) or you can simply start crossing roads as if they were short-depth rivers.
Even if you decide to go in June/August wich are the coldest months in Argentina, you'll have to put up with almost 27ºC almost everyday. Like I said, rain doesn't change temperature.
Althought it's not really the tempratures you should be aware of over there, it's the humidity in the air.
If you search for forecasts of the area before going there to know what to pack, don't waste your time because temperatures will be the same as in Buenos Aires (normal winter temperatures).
But it's the humidity that adds to a good 25ºC or 27ºC celsius degrees.
The soil of this province is not brown as it is anywhere else, it's red, due to the high content of iron in the ground.
Structure Of The City
One characteristic of this city are its hills.
In general Argentina's cities are situated in flat lands.
But Puerto Iguazú is a clear exception to this, having hills everywhere and making going anywhere a really difficult and tiring task at the beggining.
As an Argentinian brought up in the most flatened flatness of Buenos Aires I found the city a hell in that sense.
But the English side of the story didn't find it strange nor uncomfortable.
Anwyay, there's always a bus that can take you anywhere you need.
The city is not big at all. But it is bigger than a map of it might make you think.
You'll see everything is different over there and even the simplest thing will look wildly tropical.
The redness of the soil, the incredible size of the grass and the leaves of the trees, the streets made of thin triangular black stones, the constant warm air...
This city is more than used to European tourists and so they have all the facilities you might need.
It's easy to get anywhere and most important of all: you CAN get anywhere you need.
There will always be a bus to anywhere you need to go...unlike in other parts of Argentina.
Also, restaurants offer "tourist menus" for those who want to make the most out of every penny and are not on a luxurious holiday.
