Buenos Aires is flat and grid-laid, which makes it one of the easiest big cities in South America to cover entirely on foot, and each of its historic barrios rewards a slow, dedicated walk rather than a rushed pass-through on a bus. Microcentro to Congreso, the civic axis Start at Plaza de Mayo, taking in the Casa Rosada, the Cabildo, and the Metropolitan Cathedral, then walk west along the Parisian-style Avenida de Mayo, passing Café Tortoni and Palacio Barolo, to the neoclassical Palacio del Congreso on Plaza de los Dos Congresos.

Buenos Aires reads its own history in its architecture, from the pink executive palace to the necropolis where the city buries its icons. Plaza de Mayo and the Casa Rosada The political heart of Argentina since 1580, Plaza de Mayo is flanked by the pink Casa Rosada, the colonial Cabildo, and the neoclassical Catedral Metropolitana, which holds the mausoleum of General San Martín. Since 30 April 1977, the Madres de Plaza de Mayo have gathered here every Thursday at 15:30, marching counter-clockwise around the Pirámide de Mayo in white headscarves to demand justice for their disappeared children and grandchildren; the headscarf symbol is painted permanently into the flagstones around the pyramid.

Buenos Aires runs on close contact, unhurried dinners, and a dance built for two, which makes it one of the easier cities in South America to slow down in as a couple. A tango salon, not a stadium show El Querandí, in an intimate 1920s salon at Perú 302, San Telmo, traces tango from 1860 to Piazzolla with a live six-piece orchestra, running roughly US$60-75 show-only or US$95-125 with a multi-course dinner.

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.

The best family stops in Buenos Aires trade formal sightseeing for hands-on time: rescued capybaras, a mini-city built for kids, and a dome full of stars. Ecoparque, Plaza Italia The old Buenos Aires zoo closed its cages permanently in 2016 and reopened as the Ecoparque, an 18-hectare rescue and rehabilitation park at Av. Las Heras and Av. Sarmiento (Subte Line D, Plaza Italia) where mara, capybaras, guanacos, and native waterbirds roam in open habitats rather than pens.

Buenos Aires sits at the edge of a delta on one side and the flat Pampas on the other, and both are a single train ride away, no rental car required. Tigre and the Paraná Delta The electric Mitre Line train leaves Retiro station for Tigre every 15 minutes, a 55-minute ride for about ARS 887 on a SUBE card. In Tigre, board a public wooden lancha colectiva from the Estación Fluvial for ARS 3,000-5,000, or a one-hour panoramic catamaran cruise for roughly ARS 15,000-20,000 (about US$12-15).

The best guided stops in Buenos Aires are the ones you cannot see properly without one: a working opera house, a stadium tunnel, and a lighthouse dome 22 floors up. Teatro Colón, from the inside Guided architectural tours of Teatro Colón, one of the world’s top acoustic opera houses, run every 15 minutes from 10:00 to 16:45, with English-language departures at 11:00, 12:00, 13:00, and 15:00. The 50-minute route covers the 2,487-seat horseshoe auditorium and the gilded Salón Dorado.

The rhythm of a porteño day is set by mate, not a checklist: a thermos, a gourd, and a bench in the shade cover most of an afternoon here. Sipping mate in Bosques de Palermo Locals gather on the lawns of Bosques de Palermo (Parque Tres de Febrero) around the lakes and El Rosedal, the 400-hectare rose garden with more than 18,000 bushes, open Tuesday to Sunday 08:00-18:00 in winter and until 20:00 in summer, free to enter.

A wine region built around communal tasting menus sounds like a hard sell for a solo trip, but Mendoza’s infrastructure was never designed to require a companion, and the city is one of Argentina’s safest and most navigable for traveling alone. The self-guided Maipú bike and wine route Take the Metrotranvía light rail from Estación Central to the end of the line at Estación Gutiérrez in Maipú, roughly ARS 650 by SUBE card or contactless bank card, and rent a cruiser bike right outside the station from Maipu Bikes or Martin’s Bikes.

Come to Mendoza expecting a Spanish colonial old town and the city undersells itself. The 1861 earthquake flattened the original colonial core, so what stands today is 19th and 20th century rebuilding, done deliberately low and leafy for seismic safety. Judge it on that basis instead and a single day of walking covers real ground. Start at Plaza Independencia The four-block central square anchors the 1863 grid: artisan wood and leather stalls, street performers, and the subterranean MMAMM (Museo Municipal de Arte Moderno) beneath the plaza itself.

Mendoza sits close enough to the Andes, Chile, and its own southern desert that the temptation is to squeeze all three into rushed day trips. It’s the wrong call for most of them. Sorted by how many nights each one actually needs, here’s what rewards staying over instead of driving back. 2 to 3 nights: San Rafael and the Atuel Canyon Agencies sell this as a 14-hour day tour, 240 to 270km each way, which spends most of the day on the bus for roughly 4 hours in the canyon itself.

Wine culture runs on shared tables by default, so Mendoza’s group scene barely has to try: the region’s biggest draws (long lunches, team river trips, a festival with a 20,000-seat amphitheater) are already built around groups rather than solo visitors. Multi-course winery lunches This is the signature group ritual: 3-to-6-course seasonal tasting menus with a wine pairing per course, served at communal tables looking out over vineyard rows and the Andes.

Mendoza markets itself as an adult wine destination first, which makes people assume it has little for kids. That’s wrong, but only if you pick the right handful of things and skip one attraction every older guide still lists as open. Termas de Cacheuta’s water park 40km southwest in the Cacheuta gorge, this is the single strongest family attraction in the province: over 20 thermal pools cascading down the mountainside, dedicated children’s pools, waterslides, a sandy beach area, a lazy river and a wave pool, plus picnic areas and quinchos for a family barbecue.

Plenty of cities market a hop-on hop-off bus that turns out to be a single circling minivan on a loose schedule. Mendoza is the opposite case: it runs two genuinely separate, ticketed double-decker systems, and mixing them up is the easiest way to miss a transfer. Mendoza City Bus The open-top double-decker, run in partnership with Andesmar and City Bus AR, loops Plaza Independencia, Parque Central, the Área Fundacional and its Museo y Plaza Pedro del Castillo, Casa de San Martín, La Enoteca in the Civic Center, Calle Arístides Villanueva, the Portones del Parque and Fuente de los Continentes in Parque San Martín, Museo Moyano, the Cerro de la Gloria summit monument, and Espacio Arizu in Godoy Cruz.

No ocean touches Mendoza, so every water-based adventure sport here happens on a mountain river or a reservoir instead, and that constraint turns out to shape the whole category more than most guides admit. Whitewater rafting on the Río Mendoza The river runs its full range through the Potrerillos valley, and the grade genuinely changes with the season: Class III to IV rapids during the November-to-March snowmelt peak, dropping to a milder Class II to III in the lower-water autumn window of April through June.

Buenos Aires is a South American capital with a European surface, café culture, wide boulevards, Belle Époque architecture, and a Rio de la Plata soul underneath it: dinner at 10pm, tango danced for real rather than performed, and a currency story that just went through the biggest reset in a decade.

Seven days is our 6-day itinerary plus one more museum-and-slow day, but the honest advice for a full week here is worth saying up front: past 3-4 days, Buenos Aires works better as a launch pad for the rest of Argentina, Iguazú, Patagonia, Mendoza, than as a place to keep padding.

Two days is a rushed hit-list, not the honest core, that’s 3-4 days, so say so going in and don’t try to squeeze in more than what’s below. If you can stretch it, our 3-day itinerary adds Palermo and a proper asado without feeling frantic.

The advice to bring a stack of crisp US dollars for the “blue dollar” rate is dead. In April 2025 the Milei government abolished the currency controls that created that arbitrage, and by mid-2026 the gap between the official and street rate had collapsed to roughly 0-3%.
