Every workable Argentina itinerary obeys one rule: fly between the corners, never drive them. Buenos Aires to Ushuaia is 3,000 kilometers, to Iguazu 1,300, and the bus that covers either takes a day you do not have. So instead of listing routes that look good on a map and collapse in practice, this guide runs one proven spine at three honest speeds, with the flights that hold it together booked first.
The short answer: 12 days buys Buenos Aires, Patagonia and Iguazu; 16 adds a real Patagonia or the northwest; 21 runs the country. Lock the domestic flights and the Patagonia beds before anything else.

The Argentina Itinerary Spine
The spine reads: Buenos Aires (3 nights) → fly south to El Calafate (3) → bus north to El Chaltén (2-3) → fly back through Buenos Aires → fly north to Iguazu (2) → home. Four domestic flights and one three-hour bus.
It works because each corner gets a block rather than a raid, and because Buenos Aires earns its double stop: arriving and departing through the same hinge is not wasted time when the hinge is this good a city.
Season decides the order more than preference does. Patagonia only behaves October to April, the northwest is the inverse and prefers April to November, and Iguazu works year-round with peak water November to March. Fix the Patagonian dates first and let everything else arrange itself around them, exactly as our best time to visit Argentina guide sequences it.
The 12-Day Route
| Day | Where | What |
|---|---|---|
| 1-3 | Buenos Aires | Recoleta and Palermo, San Telmo on Sunday, a tango night, steak at eleven |
| 4 | Fly to El Calafate | Afternoon arrival, Laguna Nimez birds at dusk |
| 5 | Perito Moreno Glacier | Full day on the walkways, or the mini-trekking on the ice |
| 6 | Lago Argentino | Upsala and Spegazzini by boat, or a rest-and-lamb day |
| 7 | Bus to El Chaltén | Three hours north, afternoon Chorrillo del Salto walk |
| 8 | El Chaltén | Laguna de los Tres, the big Fitz Roy day |
| 9 | Return and fly | Bus to Calafate, fly to Buenos Aires |
| 10 | Fly to Iguazu | Argentine side: lower circuit in the afternoon |
| 11 | Iguazu | Devil’s Throat at opening, upper circuit, jungle boat |
| 12 | Fly home via Buenos Aires | Buffer built in for the connection |
It is tight but honest, and the two long hikes are optional: El Chaltén rewards walkers of every level, not just the Laguna de los Tres crowd.
The 16-Day Version
Sixteen days is the version we recommend most, and it splits two ways depending on what you want. Deeper Patagonia: add Ushuaia for three nights after El Chaltén, the Beagle Channel, the Tierra del Fuego park and the end-of-the-world framing that no other stop delivers. Or add the northwest: fly Buenos Aires to Salta and spend four days on the coloured mountains, Purmamarca, the Humahuaca gorge, the Hornocal ridge and a Cafayate wine afternoon, which is the country’s best-value region and its most photogenic drive.
Both versions keep the same twelve-day skeleton underneath, so nothing gets cut, only added. The northwest option has a season caveat: it runs April to November, which is precisely when Patagonia is closing, so this combination works best in the shoulder months of October, November, March and April.
The 21-Day Full-Country Route
Three weeks runs the whole thing without surgery: Buenos Aires, the full Patagonia block including Ushuaia, Iguazu, the northwest, and Mendoza for three days of Malbec under Aconcagua. That is four flights becoming six, so the booking discipline matters more, not less.
It is also the length where an add-on earns its place: Peninsula Valdés for the southern right whales between June and December, or Bariloche and the lakes if your dates fall in the Patagonian summer. Backpacking Argentina on this route swaps some flights for the excellent cama suite overnight buses and adds four or five days.
The most-searched shorthand, an argentina itinerary 10 days long, is really this same spine minus one corner, which is why the section below treats it as its own decision rather than a trim.
If You Only Have 10 Days
Do not force the triangle. With ten days, run Buenos Aires plus one corner: either the Patagonia block, four nights across Calafate and Chaltén, which is the strongest ten-day trip Argentina offers, or Buenos Aires plus Iguazu plus Mendoza, which is gentler, flight-light and pairs the city with wine country.
Cramming three corners into ten days means two travel days out of every five, and the trip becomes a memory of airports. The full country context sits in our Argentina travel guide.

Booking the Flights That Make It Work
The national tourism board keeps regional conditions current at argentina.gob.ar/turismo. Three practicalities decide whether this itinerary survives contact with reality. First, Buenos Aires has two airports: international flights use Ezeiza, most domestic flights use Aeroparque in the city, and they are an hour apart, so never book a tight same-day connection between them.
Second, book domestic legs early, Aerolíneas Argentinas, Flybondi and JetSmart all fly the corners but Patagonian seats in January are gone by spring. Third, build a buffer day before your international departure, because national strikes occasionally pause flights and Patagonian weather delays the southern legs, a habit our safety guide explains in full.
What Each Version Costs
Realistic mid-range planning bands per person, international flights excluded: the 12-day route lands around $2,200 to $3,200 including four domestic flights; 16 days runs $3,000 to $4,300; three weeks crosses $4,500 comfortably. Backpacking Argentina compresses those by roughly 45 percent with buses, hostels and self-guided hikes, and the country rewards it, the hiking in El Chaltén is free and the empanadas are two dollars.
What no budget avoids: domestic flights and high-season Patagonia beds, the two line items that dominate every version. Currency practicalities, including the dollar question, are covered in the country guide.

Common Questions, Answered
How many days do you need for an Argentina itinerary?
Twelve days is the honest minimum for Buenos Aires, Patagonia and Iguazu with four domestic flights. Sixteen adds Ushuaia or the northwest, and 21 covers the country including Mendoza.
Is 10 days enough for Argentina?
Enough for Buenos Aires plus one corner done well, ideally the Patagonia block of El Calafate and El Chaltén. Forcing three corners into ten days turns the trip into airports.
What is the best order for an Argentina itinerary?
Buenos Aires first, then Patagonia while the weather window is open, then Iguazu, returning through Buenos Aires between legs. Fix the Patagonian dates first and arrange everything else around them.
Can you do Argentina without flying?
Within a region yes, the long-distance cama buses are genuinely comfortable. Across the country no: Buenos Aires to Ushuaia is 3,000 km, so every realistic itinerary flies the corners.
How do you get from El Calafate to El Chaltén?
A three-hour bus north on Route 40, with several daily departures in season. Most travelers base in Calafate for the glacier, move to Chaltén for the hiking, then return to fly out.
What is the best month for an Argentina itinerary?
October, November, March and April. They catch Patagonia inside its window, the northwest in its dry season and Iguazu at good flow, all with fewer crowds than the January peak.
The Bottom Line on Routing Argentina
One spine, three speeds, flights doing the heavy lifting and Patagonia setting the calendar: that is the whole doctrine of an Argentina itinerary that arrives home on schedule. Choose your speed by the leave you actually have, protect the buffer day, and the eighth-largest country on earth becomes a sequence of short, perfect chapters.
