Buenos Aires or Montevideo?
The question we get most. Here is the honest answer.
Buenos Aires or Montevideo? It's one of the first questions travelers ask when planning South America's Southern Cone. There's no single answer — it depends on what kind of trip you want, your budget, and what draws you most: cultural depth, ease of movement, food, or pace. This comparison lays out both cities honestly.
Buenos Aires draws those who want the Paris of Latin America. Montevideo draws those who want a small, calm capital. Both have their own logic, and choosing one doesn't mean missing out — they're different experiences. In many cases the smartest move is combining them in a 7-day itinerary, and this guide includes exactly that.
Here you'll find climate data, average costs, best travel months, traveler profiles, and a 7-day combo itinerary for those who want both. Topic: Río de la Plata · South American capitals.
Currency.
Argentina has a chaotic exchange system — official rate versus the parallel "blue" rate. Exchanging at cuevas can save you 40-60%. Uruguay has a straightforward stable peso.
Identity.
Buenos Aires is a European city transplanted to South America — Beaux-Arts architecture, corner cafés, tango. Montevideo is its quieter, smaller cousin.
Day trips.
From BA: Tigre delta, Mendoza wine country, Bariloche, Patagonia. From Montevideo: Punta del Este, Colonia del Sacramento.
Who each one is for.
