Start at Café Tortoni on Avenida de Mayo, ideally around 8:30–9:00am. This is one of the city’s classic old cafés, with marble tables, dark wood, and a wonderfully theatrical porteño atmosphere; order coffee with medialunas or a simple breakfast and allow about an hour. It usually opens from early morning, but hours can vary, so check on the day. From there, walk roughly 10 minutes north along Avenida de Mayo toward Plaza de Mayo, taking in the ornate façades and dome-topped buildings along the way.
Spend late morning in Plaza de Mayo, Buenos Aires’ main civic stage, with Casa Rosada facing the square. Afterward, cross to the Catedral Metropolitana de Buenos Aires, whose interior is free to enter and generally open during weekday daytime hours; allow about 45 minutes to see the chapels and the mausoleum of General José de San Martín. Then continue to the nearby Cabildo de Buenos Aires, directly beside the cathedral. Its museum is a good one-hour stop for colonial history and the independence period; admission is usually modest, though museum hours can change, so verify locally. The three sights are all within a few minutes’ walk, making this a pleasantly compact morning.
For lunch, stay around Monserrat or walk toward Microcentro rather than planning a formal detour—Café El Querandí is a convenient traditional option near the historic center, while Las Cuartetas is useful for a quick pizza or empanada if you want to keep moving. After lunch, head to Galerías Pacífico, about 15 minutes on foot from Plaza de Mayo via Florida, or take a short taxi/Cabify ride if your feet need a break. Spend an hour or so admiring the grand beaux-arts building and its painted dome murals, then browse the shops. The mall generally operates roughly 10:00am–9:00pm on weekdays. Leave the rest of the afternoon open for a slow walk along Florida and nearby streets; keep your phone and wallet secure in crowded pedestrian areas.
Take a taxi or Cabify around 8:30am for San Telmo Market; from central Buenos Aires it usually takes 15–25 minutes, though weekday traffic can stretch that. Start with the market’s covered halls and surrounding stalls, allowing about two hours to browse antiques, vintage posters, leather goods, pastries, and empanadas. The market generally opens from around 10:00am, and the atmosphere is liveliest before lunchtime. From there, walk roughly 10 minutes through San Telmo’s old streets to El Zanjón de Granados. Its guided tour, usually offered during daytime opening hours, descends beneath restored colonial houses into an unexpectedly extensive network of tunnels; book ahead if possible, as tours can sell out and schedules vary.
Continue a few minutes on foot to Plaza Dorrego, the neighborhood’s historic heart. Take a relaxed 45-minute pause at an outdoor table and watch for tango dancers, particularly around the weekend, when performances are most consistent; on a Wednesday, the square is quieter but more pleasant for people-watching. Then take a short taxi or Cabify ride—about 10–15 minutes, depending on traffic—to El Obrero in La Boca for an early lunch. This old-school porteño restaurant is atmospheric rather than polished, with generous traditional dishes and football memorabilia; allow 1½ hours and budget approximately US$20–35 per person. Cash or a locally issued card can be useful, and confirming today’s opening hours is wise.
After lunch, walk or take a brief taxi ride toward Fundación Proa, beside the colorful Caminito area. Allow about 1½ hours for the contemporary exhibitions and the building’s excellent river-facing café terrace. Keep valuables out of sight around the busiest Caminito blocks and avoid wandering far into quieter streets after the galleries close; arrange your return Cabify from the main tourist zone, ideally before dusk.
From San Telmo, take a taxi or Cabify around 8:00am toward Recoleta; allow 20–35 minutes in weekday traffic. Ask to be dropped at Plaza de las Naciones Unidas, where Floralis Genérica is best seen in the softer morning light. The enormous stainless-steel flower is intended to open and close with daylight, though its mechanism has not always operated reliably, so treat the sculpture and the surrounding lawns as the main attraction. Allow 30 minutes, then walk about 15 minutes along Avenida Figueroa Alcorta to the Museo Nacional de Bellas Artes. It generally opens late morning—check the exact 2026 schedule before setting out—and admission to the permanent collection is typically free; give yourself around two hours for its strong collection of Argentine art alongside European masters.
Walk roughly 10 minutes through Recoleta to Recoleta Cemetery, entering from Junín. Set aside 1½ hours to wander its maze of elaborate mausoleums, looking for the tomb of Eva Perón as well as the quieter corners beyond the main paths. The cemetery usually opens in the morning and closes in the early evening, with last entry sometimes earlier, so arriving after lunch keeps the day comfortable without leaving it too late. From there, it is about a 12-minute walk to El Ateneo Grand Splendid on Avenida Santa Fe. This former theater is much more than a photogenic bookshop: browse the boxes and stalls beneath the painted ceiling, and have a coffee in the stage café if you want a pause before dinner. Expect roughly an hour; bookshop hours are commonly from late morning into the evening, but confirm on the day.
Take a taxi or Cabify from El Ateneo Grand Splendid to Don Julio in Palermo Viejo, usually 15–25 minutes depending on traffic. This is the one meal to reserve well ahead—arrive for your booked time rather than relying on a walk-in, and budget approximately US$50–100 or more per person depending on wine. Order a cut of Argentine beef to share, a modest selection of sides, and a Malbec; the restaurant is celebrated, but the experience is best when you do not over-order. After dinner, stroll through Palermo Soho for about an hour, especially around Gorriti, Honduras, and Armenia, where boutiques, murals, and lively bars give the neighborhood its evening energy. Keep valuables close on the walk and use a Cabify for the return if the streets begin to quiet.
