Founded in 1582 by the Spaniards, Salta is one of Argentina’s oldest and most attractive cities. Salta has a pleasant subtropical climate and has retained more of its colonial buildings than any other city in Argentina. Its location, surrounded by forested mountains up in the Lerma Valley at 1150 metres, makes for a good base from which to explore both Cachi and the Calchaqui Valleys to the south, and Juyuy and the Quebrada de Humahuaca to the north.
