Hi triptrop,
            
            We have lots of 
information about Argentina. You can start there to read about highlights, customs, food, how to get there, etc...
            
            My favorite places in Argentina are:
            
              - foz do iguazu
- 
                patagonia
              
- peninsula valdes
- perito moreno
- san martin de los andes
- 
                ushuaia
              
Best wishes,
