I entered Argentina from Mendoza town side using the bus company CATA International. Although I started in Chile it was only after a few hours when we reached border crossing in the Andes. The views were spectacular and the experience one cannot miss out on while traveling in this region. Not too far, Aqoncacua sits proudly and entices hikers to conquer it.
As most of the bus ride across Argentina took the considerable amount of time, I added this experience as a separate post with some photos.
