Buenos Aires in Three to Five Days
Three days covers the city center comfortably; five lets you add the delta and the Pampas without rushing either.
Days 1-2: the city center
Start at Plaza de Mayo, with the Casa Rosada and the colonial Cabildo, then walk Avenida de Mayo to Café Tortoni and Palacio Barolo. On day two, cross to Puerto Madero for the Puente de la Mujer and a waterfront lunch, then head north to Recoleta for the Museo Nacional de Bellas Artes, free to enter, and the cemetery where Eva Perón is buried (foreign admission ARS 24,030, card only, Argentine residents free with DNI, current hours at buenosaires.gob.ar ). Spend an evening in Palermo Soho or San Telmo, timing a Sunday for the Feria de San Telmo, which runs 12 blocks down Calle Defensa. Guided city walks covering these same blocks are bookable on GetYourGuide .
Day 3: La Boca and a tango night
Take a taxi directly to Caminito in La Boca, stay within the painted blocks, and leave by taxi before dark; the surrounding residential streets carry a real robbery risk once police patrols thin out after 18:00. In the evening, catch a tango show at El Querandí or Café Tortoni’s basement stage, both in San Telmo, or book a table for the reopened Esquina Carlos Gardel production on Calle Florida.
Day 4: Tigre and the delta
Ride the Mitre Line train from Retiro to Tigre, about 55 minutes for ARS 887 on SUBE, and spend the day on a lancha colectiva or catamaran through the Paraná Delta’s channels, stopping at Puerto de Frutos for the crafts market. This is a full day trip on its own; it does not combine cleanly with anything else in the city center.
Day 5: Colonia del Sacramento or San Antonio de Areco
With a passport in hand, take a Buquebus or Colonia Express catamaran across the Río de la Plata to Colonia del Sacramento, a 1 hour 15 minute crossing to a UNESCO-listed old town, for a night away rather than a rushed same-day return. Buquebus schedules and fares are listed at buquebus.com . Alternatively, head to San Antonio de Areco for an estancia asado and gaucho demonstrations, about 1.5 to 2 hours from Retiro by bus.
What does not belong in this itinerary
Mendoza is 1,000 kilometers west and needs a short domestic flight from Aeroparque; it is a trip of its own, not a slot inside a Buenos Aires week. The same goes for Iguazú and Patagonia: treat any of them as where you go after Buenos Aires, not a day carved out of it.
The verdict
Five days holds together if day four (Tigre) and day five (Colonia or Areco) each stay a full day rather than being split. For single-day versions of each excursion, see the day trips guide , and for hotels across these neighborhoods, compare options on Booking.com .
Before you go
Load a SUBE card on day one; it covers the Subte, city buses, and the Mitre Line train to Tigre, and none of them sell single paper tickets any more.
