Public transportation in Buenos Aires is affordable and easy to navigate. The Subte (subway) is the quickest and most affordable way to travel within the city. A single ride costs about $0.90 USD, and a rechargeable SUBE card can be purchased at any station. Taxis are also readily available, with a starting fare of $1.60 USD and $0.16 USD per kilometer. Travel time between locations will vary depending on traffic, but all destinations on this itinerary are within a 30-minute drive of each other.
If you have more time, consider adding a visit to the Recoleta Cemetery, where many of Argentina's most notable figures are buried. For those who are wine lovers, try a wine tasting tour in the nearby Mendoza wine region. If you only have one day, focus on exploring the historic center and improving your tango skills at a local milonga. Lastly, always keep an eye on your belongings and be aware of your surroundings, as pickpocketing and theft are common in tourist areas.
