For all those who are driving or are about to rent a 4wd vehicule.
The pass of Abra del Acay in route 40 is open, it connects Cachi with San Antonio de los Cobres, though in very poor conditions at the time. I advice anyone that wants to do it to have a 4wd else don´t even think of it pls!
The road is spectacular and allows you once you have reached the pass at almost 5000 mts over sea level to have an amazing view of the Puna (Argentine altiplano) as well as the far distant satflats.
For any more info don´t hesitate to contact me.
