If you are in town for the Buenos Aires long weekend, you have landed on a good one. Because Monday 17 August 2026 is the Paso a la Inmortalidad del General San Martin holiday.
Which turns Saturday 15 to Monday 17 into three full days off. That extra day gives you room to mix a big arena concert with a night at the opera.
A wander through free museums and a lazy Sunday of street fairs and regional food. We have pulled together the events we could confirm, with dates.
Venues and what you will actually pay, so you can plan before the city fills up.
Planning your Buenos Aires long weekend
The holiday on Monday marks the anniversary of the death of General Jose de San Martin. The soldier who led Argentina, Chile and Peru to independence.
It is a moveable feriado fixed to the third Monday of August. And in 2026 that lands on the 17th, giving locals and expats alike a proper three-day break.
The nice thing about this particular weekend is how much of it is free or cheap. You can happily fill all three days on a small budget, then splurge on one big night if you fancy it.
Most of what follows sits within the city itself, easy to reach on the Subte or a short taxi ride. Below we run through the headline concerts first, then the opera, the museums.
And the Sunday and holiday fairs where the food is, followed by a few practical tips on tickets, money and getting around.
Three big nights at Movistar Arena
The anchor of the weekend is Movistar Arena, the city’s main indoor venue, at Humboldt 450 in the Villa Crespo neighbourhood. It has a different headliner on each of the three nights.
So there is a good chance one of them is your thing. On Saturday 15 August, Soda Stereo return with their ‘Ecos’ production, the tribute show built around the band’s classic catalogue.
Tickets start at around ARS 70,000, roughly US$47. On Sunday 16 August, the Panamanian legend Ruben Blades brings his ‘Fotografias’ tour, with tickets from about ARS 45,000, or US$30.
The holiday Monday, 17 August, belongs to La Konga, the cuarteto act that has become one of the country’s biggest live draws. With seats from around ARS 55,000, about US$37.
Buy through the official Movistar Arena website rather than resellers, and note that prices rise as the cheaper sections sell out.
A night at the opera: Verdi’s Otello
If you would rather dress up for something grand, the Teatro Colon is staging Giuseppe Verdi’s ‘Otello’ over the weekend. The opera house, at Cerrito 628 in the Microcentro, is one of the great theatres of the world.
And worth the visit for the building alone. There are two performances in your window: Saturday 15 August at 8:00pm and Sunday 16 August at 5:00pm.
With more dates running later in the month. Ticket prices vary widely by seating section, from affordable upper-gallery seats to pricey stalls, so check the current bands when you book.
Tickets are sold through the Teatro Colon’s own box office and official website. If the opera itself feels like a stretch.
The theatre also runs guided tours most days, a lovely lower-commitment way to see inside.
Free and low-cost museums
Museums are where the long weekend gets cheap. The Museo Nacional de Bellas Artes, the national fine-arts museum at Av.
del Libertador 1473 in Recoleta, is free to enter, with donations welcome. It opens Saturday 15 and Sunday 16 August from 10:00am to 8:00pm.
One catch worth planning around: Bellas Artes closes every Monday, holiday or not, so it will be shut on Monday 17. Do that visit on the Saturday or Sunday instead.
For contemporary and Latin American art, MALBA in Palermo, at Av. Figueroa Alcorta 3415, stays open right through the long weekend, Thursday to Monday from noon to 8:00pm, including the holiday.
General admission is about ARS 12,000 (US$8), with a reduced ARS 6,000 (US$4) for students. Teachers and retirees, and free entry for young children.
Sunday fairs and where to eat
Sunday is fair day in Buenos Aires. In the cobbled heart of San Telmo, the weekly Feria de San Telmo spreads antiques.
Crafts and food stalls along Calle Defensa and around Plaza Dorrego from about 10:00am to 5:00pm. It is free to wander, and the surrounding cafes and parrillas are a fine place to graze.
Further out, the Feria de Mataderos is the one to seek out for regional cooking and folk culture. Held opposite the old livestock market in the Mataderos neighbourhood, it runs on Sundays and public holidays from 11:00am to 8:00pm.
Which means it is on both Sunday 16 and the Monday 17 holiday. This is the fair for empanadas, locro, grilled meats and dulces from around the country, with live folk music and gaucho dancing.
Entry is free; you simply pay for what you eat and drink. Which makes it an easy, low-cost plan for a slow afternoon.
Tickets, timings and how to buy
For the arena shows, buy directly from the Movistar Arena website. The Teatro Colon sells its opera tickets through its own site and box office.
Both tend to release seats in price tiers, so the earlier you book, the more of the cheaper sections are still available. For the museums and fairs you need nothing in advance.
Bellas Artes lets you walk straight in for free. While MALBA is quicker if you buy your timed ticket online before arriving, especially over a busy holiday weekend.
Doors at concerts usually open an hour or two before the billed start time. And Argentine shows often begin late, so do not panic if the room is quiet at the printed hour.
Money and getting around
A quick word on money, because Argentina has more than one exchange rate. In mid-August 2026 the official rate sat near ARS 1,465 to the US dollar and the parallel.
Or ‘blue’, rate near ARS 1,521, both quoted around 11 August. We have used a round 1 USD to 1,500 ARS for the conversions above.
So treat the dollar figures as a guide rather than a fixed price. Cards are widely accepted at big venues and museums, but the Sunday fairs run largely on cash.
So carry some pesos for empanadas and craft stalls. A rechargeable SUBE card is the cheapest way to ride the Subte and buses across the city.
One last tip: the holiday Monday is quieter than a normal weekday, with some shops and offices closed. So build your plans around the venues and fairs that we have confirmed are open.
A weekend that stretches your pesos
Add it up and the Buenos Aires long weekend gives you a genuine range: a world-class opera house, three arena headliners. Free national art and two of the city’s best-loved fairs, most of it walkable or a short ride apart.
You could spend big on a concert or coast through all three days on free museums and fair food. Either way, the extra San Martin holiday is the gift that makes it work.
So pick your one splurge and let the rest fall into place.
