There are numerous options for tours throughout Argentina with a plethora of agencies specializing in different areas. The most popular choices are Patagonian cruises, self-drive options, wine tours, Iguazú waterfalls tours, Lake District tours, or polo and tango tours. Sports-oriented tours include fishing, shooting, horseback, cross-country skiing, hiking and adventure opportunities. Tours can last as few as two days or as long as a month, and it is wise to book in advance as there is usually limited room available on an expedition.
