I'm planning a trip to visit 4 countries which is Argentina, Brazil, Bolivia & Peru all within 21 days. The starting point is Sao Paulo, Brazil. We will be in group of 5 persons.
Planned schedule as below:
Sao Paulo - Rio - Manaus - Lima - Nazca - Cuzco - Macchu Picchu - Puno - La Paz - Salar de Uyuni - Glaciar Perito Moreno - Buenos Aires - Iguassu Falls - Sao Paulo.
We are tight for both time and budget. Would like to see if there's someone who can gives us suggestions.
Many Thanks for your attention and in case you are interested in visiting Hong Kong, I may gives you advise for meals, sightseeing and accomodation for backpackers.
You will see bugger all, so I presume you are doing it for the Frequent Flyer points, or you are flying on an F-16 at Mach 2 between cities/sites!!!
Salar de Uyuni to San Pedro de Atacama in Chile takes 4 days for a start.
How are you travelling? Plane, car, bus or a combination?
The trip does seem a bit stressed, although I did Sao Paulo - Asunsion (Paraguya), Salta (Argentina), San Pedro Atacama (chile), Iquique, Arequipa (Peru), Cusco, (5 days Salkantay trek), Machu Picchu, Puno, La Paz (Bolivia), Cochabamba, Santa Cruz, Corumba (BR), Bonito and Sao Paulo in 30 days by car. But, if you're travelling by plane+bus I think you'll have difficulties doing all the suggested parts in just 21 days. Cut out some places; eg. Nazca, Lima.
There are also tours from La Paz to Salar to Uyuni. You don't need
to go to San Pedro de Atacama, which I do not recommend (the dryest
dessert in the world and not that pretty as other desserts).
That really is a lot jammed in over 21 days. Try spending some more time in a fewer places otherwise you may not get to see that much at all! For example, not even 1 week is enough time to see the whole of Buenos Aires.
