Overview
Argentina is a country of enormous geographical range, and its list of major cities tells that story on its own: the capital Buenos Aires in the east, the coastal resort city of Mar del Plata, the far southern outpost of Ushuaia, and a spread of northern and interior cities including Córdoba, Santa Fe, Corrientes, Posadas, Resistencia, Paraná, Formosa, San Miguel de Tucumán, Santiago del Estero, Neuquén and San Luis, plus Avellaneda and La Plata within reach of the capital itself.
Spanish is the language spoken everywhere, and the currency is the Argentine peso (ARS). Because the country stretches from northern provincial cities down to Ushuaia in the far south, any trip has to be planned around which of these zones you actually want to see — the capital and its surrounds, the northern interior cities, or the long haul south.
This guide works city by city and region by region, using only Buenos Aires, Córdoba, Santa Fe, Corrientes, Posadas, Resistencia, Paraná, Formosa, La Plata, San Miguel de Tucumán, Ushuaia, Mar del Plata, Santiago del Estero, Neuquén, San Luis and Avellaneda as the anchors, since these are the major cities that structure travel through the country.

How Argentina breaks down
Buenos Aires, the capital, sits on the eastern side of the country and is the natural entry point for most visitors. Close by are La Plata and Avellaneda, both major cities in their own right that sit within the broader Buenos Aires area, giving travellers based in the capital an easy way to see more of this part of the country without a long journey.
To the north lies a cluster of cities that make up Argentina's northern interior: Santa Fe, Corrientes, Posadas, Resistencia, Paraná and Formosa, along with San Miguel de Tucumán and Santiago del Estero further into the interior. These cities represent the northern reach of the country and give a very different flavour to the capital or the south.
Córdoba and San Luis represent the interior proper, inland from the coast and the capital, while Neuquén marks a shift toward the country's southern reaches. At the far end of the country is Ushuaia, the southernmost of Argentina's major cities, with Mar del Plata sitting on the coast as the country's seaside city.
Because these cities are spread across such different latitudes — from the northern interior down to Ushuaia in the far south — Argentina genuinely functions as several distinct kinds of trip depending on which cities you combine.
How many days do you need
A short first trip to Argentina realistically centres on Buenos Aires, with the option of adding La Plata or Avellaneda as an easy extension given their proximity to the capital. Even a few days gives time to get a feel for the capital before deciding whether to venture further.
With more time — a week to ten days — it becomes worth combining Buenos Aires with one other major region: either the interior via Córdoba and San Luis, the coast via Mar del Plata, or a push north to Santa Fe, Corrientes or Resistencia.
For two weeks or more, Argentina's scale really opens up. This is when it makes sense to link the capital with the northern interior cities (Santa Fe, Corrientes, Posadas, Resistencia, Paraná, Formosa, San Miguel de Tucumán, Santiago del Estero), the interior (Córdoba, San Luis, Neuquén), and the far south (Ushuaia), rather than trying to see everything on a shorter visit.
Getting around Argentina
Given the distances between Argentina's major cities — from Ushuaia in the deep south to the northern cities like Formosa, Posadas or San Miguel de Tucumán — domestic flights are generally the most practical way to cover the country's length. Buenos Aires functions as the hub most routes run through or connect via.
Road travel connects the cities within closer reach of one another, such as Buenos Aires with La Plata and Avellaneda, or the interior cities of Córdoba and San Luis, and is a reasonable way to move between neighbouring cities in the same broad area.
For the northern cluster — Santa Fe, Paraná, Corrientes, Resistencia, Posadas and Formosa — travelling overland between them is a common approach, since they sit relatively near one another in the north of the country, whereas reaching the far south at Ushuaia or the coast at Mar del Plata is generally best done by air given the distances involved.
A sample route
Start in Buenos Aires, the capital, allowing time to explore the city itself before making a short trip out to La Plata and Avellaneda, both close enough to fit into the early part of a trip.
From Buenos Aires, head inland to Córdoba, then on to San Luis, covering Argentina's interior cities before either returning east or continuing the journey.
From the interior, move north to take in Santa Fe, Paraná, Corrientes, Resistencia, Posadas and Formosa in turn, tracing the northern cluster of cities, with San Miguel de Tucumán and Santiago del Estero as further stops in the north.
To finish, fly south to Ushuaia at the far end of the country, or alternatively divert to the coast at Mar del Plata — either makes a strong final leg given how different in character they are from everything that comes before, and Neuquén can be worked in en route depending on how the southern leg of the trip is planned.
When to go
Argentina's major cities span such a wide range of latitude — from the northern interior cities down to Ushuaia in the far south — that seasons play out very differently depending on where you are in the country. As Argentina sits in the southern hemisphere, its summer runs over the months that are winter in Europe, and vice versa.
This matters most for a trip that includes Ushuaia in the south and the northern cities like Formosa or Corrientes at the same time, since the timing that suits one end of the country won't necessarily suit the other. Planning around which cities you're prioritising — north, south, coast or interior — is the most sensible way to decide when to travel.
Costs and money
The currency throughout Argentina is the Argentine peso (ARS). It's used in Buenos Aires and in every one of the country's other major cities, from Mar del Plata on the coast to Ushuaia in the south and the northern interior cities such as Santa Fe, Corrientes and Posadas.
Costs will naturally vary between a capital-city trip centred on Buenos Aires and a longer multi-city itinerary taking in the interior and the north, simply because of the added domestic flights or road travel needed to connect cities as far apart as Ushuaia and Formosa.
Language and etiquette
Spanish is the language spoken across Argentina, from the capital Buenos Aires through every one of the major cities named here — Córdoba, Santa Fe, Corrientes, Posadas, Resistencia, Paraná, Formosa, La Plata, San Miguel de Tucumán, Ushuaia, Mar del Plata, Santiago del Estero, Neuquén, San Luis and Avellaneda.
Travelling between such a wide spread of cities, from the northern interior to the far south, having at least some basic Spanish will make journeys and day-to-day logistics considerably smoother, particularly outside the capital.
