Irene, if you have some time, I'd recommend you to get off the bus in Tucuman and travel along the Calchaqui Valley by bus stopping in every small town you may find on the way: Tafí del Valle, Amaicha del Valle, Quilmes, Santa María (Catamarca) arriving to Cafayate (Salta). The company Aconquija provides a ticket that allows you to get down the bus and continue the next day or whenever you want to continue. Make sure you dont have a tight schedule when taking Andesmar from Iguazu as sometimes they may take more than 24 hours and as it is the only service between those cities, try to purchase your ticket in advance, specially during high season. Just to let you know, the buses are not the best available in Argentina and the route is not that enjoyable, but well... it is the only option...
