This is a great way to combine two of the most interesting and diverse nations of South America. Brazil and Argentina compliment eachother naturally and this trip is a great way to see some of the best of both.
You start at the Brazilian Beach destination of Buzios before stopping at the iconic City of Rio de Janeiro. Then it's a flight down to Iguassu, arguably the most stunning waterfalls in the world, set in lush tropical rainforest. Your final stop is the rich mix of modern cosmopolitan and historical grandeur that is Buenos Aires.
This is an example plan which we would be happy to customise to suit your requirements
Buzios 4 nights
Rio de Janeiro 3 nights
Iguassu Falls 2 nights
Buenos Aires 3 nights
