The opera house that singers and conductors rank among the best-sounding rooms in the world — a gilded horseshoe auditorium opened in 1908, a dome painted by Raúl Soldi and a Golden Hall straight out of Versailles. See it on a guided tour by day, then come back for a performance.
A city of marble and bronze in the heart of Recoleta: nearly five thousand family vaults lining shaded avenues, the black-granite tomb of Evita, presidents, poets and the haunting stories of Rufina Cambaceres and Liliana Crociati. Foreign visitors pay a modest entry fee.
The finest museum of modern Latin American art anywhere, celebrating its 25th anniversary in 2026: Frida Kahlo, Tarsila do Amaral's Abaporu, Antonio Berni, Xul Solar and Diego Rivera in a light-filled modern building in Palermo. Closed Tuesdays; half price on Wednesdays.
FreeArgentina's national art museum, free to all: the largest public collection of Argentine art, plus Goya, El Greco, Rembrandt, Manet, Monet, Rodin and Van Gogh's Le Moulin de la Galette, in a former pumping station on Avenida del Libertador. Closed Mondays.
FreeThe painted tin houses of the old immigrant port, a pedestrian street turned open-air museum, tango dancers on the corners and the roar of Boca Juniors' Bombonera a few blocks away. Colourful, crowded and touristy — go by day and stay within the visitor area.
FreeEvery Sunday, Calle Defensa becomes a mile of antiques, crafts, vinyl, soda siphons and street tango, centred on the old colonial square of Plaza Dorrego — the best day out in the city's oldest barrio, with the iron-and-glass Mercado de San Telmo next door.
FreeThe political stage of Argentina: the pink presidential palace where Evita addressed the crowds, the colonial Cabildo, the cathedral with the tomb of San Martín and the square where the Mothers of Plaza de Mayo still march on Thursdays. Free weekend palace tours, booked online.
FreeA 1919 theatre turned into one of the most beautiful bookshops in the world: shelves fill the boxes and balconies, a painted ceiling arches overhead and the café sits on the old stage behind the red curtains. Free to enter on Avenida Santa Fe, open late every day.
The big, polished tango dinner show: around forty dancers and live musicians in a vast theatre in Barracas, tracing the story of tango from the port to the stage, with folk dance, costumes and an optional steak dinner with wine. Spectacular rather than intimate — and a great first night.
An hour north of the city, the river town of Tigre opens onto a vast green maze of channels and islands where houses stand on stilts, boats are the buses and rowing clubs line the banks. A small-group boat tour is the easiest way to see it; the craft market and art museum complete the day.
Cross the Río de la Plata by fast ferry to a UNESCO-listed Portuguese colonial town in Uruguay: cobbled lanes, a lighthouse beside convent ruins, bougainvillea over low stone houses and sunset over the river. About an hour and a quarter each way — bring your passport.
FreeThe green lungs of Buenos Aires: lakes with pedal boats, more than eight thousand roses in the Rosedal, an Andalusian patio from Seville, the planetarium and, across the road, the serene Japanese Garden. Free to roam, with a small fee for the Japanese Garden.
