Sansalvador de Jujuy is a perfect jump off point for exploring some of the most desolate and wonderful scenes in the world. At the moment not many non-Latin Americans around at all and the tourism is mainly Argentinians, Bolivians and Brazillians.
Most people you will incounter in the Jujuy region will speak only Spanish. There are however large numbers of people from Bolivia and Peru who speak Quechua.
From Salta its only a two hour bus journey for 300 (Flecha or Balut, May 2019) or share a remis and grab a empanada while your waiting some of the best meat empanadas are sold just across the road from the bus station where the remise leaves from. The bus station is a fifteen minute slow walk to the centre of town and a taxi should cost no more than three pesos. When you arrive, walk the length of the makeshift market where you can buy food clothes and coca. The street food near the bus stop is excellent and cheap (4 empanadas for 1 peso). Cross the bridge and just keep walking. The main street is Belgrano.
there are so many different price ranges to choose from and one of the most upscale is miralejos sitting facing the Plaza Belgrano, not only is the food the best in Argentina so is the wine and the coversation.if you want to try some of the sweetest desserts go to casa bindo. You might never finish your dessert but its worth it for the sugar high at least.
theres quite a few hostels in jujuy but none like yok wahi on la madrid the staff enjoy working there and it makes a real difference... whether you speak good Spanish or not these guy will help you find mountains get drunk and laugh a lot!
