Of course this depends on whether you love trekking, you’re learning Spanish, backpacking or digital nomading… but on average we believe 1-3 days is the right amount of time.
In this case, unlike for places like Buenos Aires or Iguazú, you need to pay attention: Lonely Planet forum suggest 4-14 days, Fodors reminds you you definitely need to hire a car and visit the whole region, yes, they are all talking about the whole REGION/PROVINCE (with nights in different locations) and not just the town itself.
But let’s now break down what we believe are the ideal stay lengths depending on your trip objective. We spent 10 days in Salta working as digital nomads so hopefully we can help you with your trip planning!
