What should I avoid in Buenos Aires?

The first mistake happens at Ezeiza. Unlicensed drivers crowd the arrivals hall offering flat fares to Palermo or Recoleta, and they'll quote double what the metered ride costs. Walk past them to the official remise counters near the exit. Tienda León runs a bus to Terminal Madero every 30 minutes for a fraction of the taxi price. From Aeroparque, the domestic airport about 4 km north of Palermo, a metered taxi to most central hotels runs under $10 USD at the September 2026 rate of roughly 1,513 ARS per dollar. Take it from the official stand outside, never from anyone who approaches you inside the terminal. The Subte connects six lines across the city center but reaches neither airport, so plan a car or bus for arrival day.

La Boca past the two-block Caminito pedestrian walkway is the most repeated safety warning in Buenos Aires, and it's earned. The painted tin houses along the 100-meter tourist strip smell like fresh acrylics and grilled choripán from the vendors at Magallanes and Del Valle Iberlucea. Walk three blocks south toward Almirante Brown and the scene changes fast. Empty sidewalks, stripped cars, and locals who will wave you back the way you came. Puerto Madero looks safe, and it is, but the waterfront restaurants charge 2-3x what the same steak costs in Palermo Hollywood or Villa Crespo. A bife de chorizo at Don Julio in Palermo runs about $18 USD, and the reservation wait there is two weeks for good reason. The same cut at a dock restaurant along Dique 3 costs closer to $25 and the meat is not better.

Buenos Aires scores 5.5/10 on TTDI's solo-traveler safety scale (see the TTDI Solo-Safety Index), with property crime in tourist corridors driving most of that figure. Counterfeit peso notes move here more freely than in most South American capitals, and the 1000 ARS bill is the denomination faked most often. Check for the watermark and metallic security thread before pocketing change from taxi drivers or street vendors. The mustard-spill scam runs daily near Plaza de Mayo, a central square since 1885, and around Recoleta Cemetery, which has drawn visitors since 1822. Someone squirts sauce on your jacket. A helpful stranger appears with napkins. Your phone or wallet vanishes during the cleanup. Two-person crew, every time. If something hits your clothes in a tourist zone, walk away without stopping. The bird-dropping variant uses the same routine near Plaza San Martín in Retiro.

Calle Florida, the pedestrian shopping street running south from Plaza San Martín, fills with leather-shop touts quoting prices 3-4x what Murillo Street in Villa Crespo charges for the same jacket. The restaurants along Florida with laminated photo menus serve reheated milanesas and weak Malbec at tourist markup. Head 10 blocks west to San Telmo or Palermo Soho and the food quality jumps. At El Sanjuanino in Recoleta, a plate of empanadas sanjuaninas costs around 4,000 ARS, roughly $2.60 USD. The kitchen has served them since the 1970s. The dough is thick and hand-crimped, and the cumin-and-paprika filling carries a warmth you can smell from the sidewalk on Posadas Street.

Buenos Aires sits at 34°S, close to the Southern Hemisphere equivalent of Los Angeles. Summer from December through February brings 35°C afternoons with humidity that clings to your skin by mid-morning. The city empties in January when porteños leave for Mar del Plata or Uruguay, and some neighborhood restaurants close for the whole month. Winter nights drop to 5-10°C, and the damp wind off the Río de la Plata cuts through light jackets. Mid-September conditions currently hover around 12°C with overcast skies and 66% humidity. The pampero, a cold front from the southwest Pampas, can drop temperatures 10°C in under two hours. The only warning is a dark band of cloud building on the western horizon.
