True, Rio is a great place to visit, and if you are careful you certainly can stay out of trouble there.
No, you can't get a true Amazon experience from Iguazu. The best way to look at the Amazon is to go to the central and northern parts of Brazil.
45 days is not a lot of time in South America. I would pick 2 or 3 places and try to get the most out of them in the time you are there, rather than spend less time in more places. For example, you could do Rio, the amazon and Iguazu, and from Iguazu cross into Argentina, and if time permits see Curitiba and Florianapolis.
I've just returned home from South America last week after spending 3 months over there. Is this your first trip there?
yea it is the first time i am visiting latin america and i am very excited about it but also nervous and confused. I have so many questions in my mind that i think its gonna blow up
anyway i think that in 45 days i can cover the basics of Brazil and Argentina, at least i hope so.
If i were you, i'd start my trip in Buenos Aires (one week) then go up to Puerto Iguazu and Foz do Iguacu...then take a bus to Rio Do Janeiro (absolutely Amazing), after that Salvador de Bahia and then Belen, from here i'd take a boat to sail through The Amazon River - Manaus and Iquitos (Peru). From Iquitos I'd take a fly to Lima and from Lima to Cusco to do the Incas trail. If you still have time consider visiting Titicaca Lake (it's between Peru and Bolivia).
thanks a lot ppati!
i will keep in mind your suggestion
