Getting around Buenos Aires

The oldest subway in South America, the subte, is a quick, cheap and efficient way to get around Buenos Aires. The buses can take you anywhere, but it may not be worth the effort to figure out the routes. Buenos Aires is great to walk around – lovely streets, plazas and parks. You can also grab a radio taxi, which is safer than street taxis. You can identify them by the plastic light boxes on their roofs. Make sure you know your destination’s address and cross street, as some drivers don’t know the city very well. You don’t need a car to get around the city, but if you drive, make sure you find out the rules of the road.

Getting from the Airport to the City

A number of private bus companies operate between the Ministro Pistarini International Airport (EZE) and central Buenos Aires; services are regular and take around 45 minutes. Public bus is cheaper but can take longer than two hours to the city centre. Metered taxis are also available outside the terminal buildings, and chauffeured cars (remises) are available for hire on the lower level of both terminals.

What is good to know if travelling to Buenos Aires?

  • Wander through one of Buenos Aires’ most important sites: the resting place of Eva Peron at the Recoleta Cemetery. The minute you walk into the grand gates of the cemetery you’ll realise that it’s not like any other you’ve ever visited. Stroll through the passageways where Argentina’s elite are buried, and explore the most ornate tombs you’ll ever see in your life; there’s even one that’s a mini replica of the Sagrada Familia.
  • The heart and soul of tango is Buenos Aires, and whether you stop into a café or a professional dance hall, tango lessons are widely available. But if you’d rather just sit back and watch then head to one of the milongas and experience an authentic tango in motion.

Weekend markets are a favourite among visitors and the Feria de Mataderos in the Mataderos barrio is the most exceptional one. Another great place to visit is the Librería Alberto Casares where you can spend endless hours rummaging through the bookstore’s impressive collection of antique books and old maps.
