Get from A to B

Buenos Aires has six subte (metro) lines, A, B, C, D, E and H, plus the Premetro light rail: more than 64 km and 108 stations. Line A (1913) was the first underground railway in South America and the Southern Hemisphere. Numbered colectivos (city buses) reach every corner of the city around the clock, helped by ten bus-only Metrobus corridors. Suburban trains run from Retiro, Constitución and Once, including the Mitre line to Tigre and the Roca line to La Plata. Pay with a SUBE card or, on the subte and colectivos, with a contactless Visa or Mastercard (also foreign cards) or a phone. Black-and-yellow taxis are everywhere, and Uber, Cabify and DiDi are widely used.

Find the right line with the city's Cómo Llego map (mapa.buenosaires.gob.ar/comollego), which also gives average trip times. Electric buses link Plaza San Martín (Retiro) with Parque Lezama through the Microcentro, San Telmo and La Boca.

  24h on most lines; less frequent at night

The city has about 300 km of bike lanes. Argentine residents keep a free weekday pass (4 rides of 30 minutes a day).

  24h

• TaxiTaxis (black and yellow)

  Hail them in the street, call a radiotaxi (considered safer) or use the city's BA Taxi app, which shows an estimated price and accepts all payment methods. The city's tariff page (checked October 2026) still lists ARS 1,920 flag fall (bajada de bandera) plus ARS 192 per 200 m or per minute waiting (ficha), with a 20% night surcharge from 22:00 to 06:00 and one free suitcase (each extra bag = 5 fichas). Decreto 309/2026 proposes ARS 2,550 flag fall and ARS 255 per ficha from October 2026 (night ARS 3,060 / 306) and ARS 3,100 / 310 from February 2027; the public hearing was on 13 October 2026, so check the meter. Fares are only in pesos.

  24h

• Ride-hailingUber, Cabify and DiDi

  All three cover the whole city and have signposted pick-up points at both airports. They worked for years in a legal grey zone; in May 2026 a city appeals court (Sala II, Contencioso Administrativo) ruled that until a specific law exists the apps and their drivers must meet taxi and remis obligations (professional licence, passenger insurance), and in September 2026 the city government announced a registration regime for transport network companies. Remises (private hire cars booked by phone at an agreed price) are the traditional alternative.

  24h

• FerryFerries to Uruguay (Buquebus, Colonia Express)

Good to know

• Register your SUBE card (online or in the SUBE app) before riding: unregistered cards pay about 1.4 times the subte fare, 1.6 times the city-bus fare and double on trains and national bus lines.
• No SUBE? Tap a contactless Visa or Mastercard (foreign cards work), phone or watch at the marked subte turnstiles and on colectivo validators: you pay the registered fare, but the Red SUBE transfer discounts apply only to the SUBE card.
• On a colectivo, say your destination to the driver before tapping: fares go by distance section.
• On trains, tap your SUBE again at the exit gate: the full fare is taken at entry and the difference refunded at the exit.
• Subte stations closed for renovation in October 2026: Medrano (Line B), Lavalle (Line C), Entre Ríos and General Urquiza (Line E).
• The subte starts at 08:00 on Sundays and holidays and the last trains leave around 22:00-23:30; on Friday and Saturday nights Line B runs to 01:30 with limited stops.
• Pickpockets and bag-snatchers on motorbikes work in Palermo, San Telmo, La Boca, Retiro, Florida street, Avenida de Mayo and around the Obelisco and the ferry terminals; in La Boca stay inside the patrolled Caminito area (UK FCDO).
• At Ezeiza and Aeroparque never take a ride offered by someone calling out in the hall; use the Taxi Ezeiza stand, an authorised remis counter, Tienda León or an app.
• Ezeiza's secondary runway closes and the main runway has restrictions from 25 October to 11 November 2026; some flights are rescheduled.
• Taxi fares are in pesos only; a fare increase (flag fall ARS 2,550 by day) was under public hearing on 13 October 2026.
• BA Ecobici is paid for foreign visitors: buy the ARS 2,100 single-ride or ARS 15,000 day pass in the app with a passport and credit card.
