I also walked up to the top of the Cerro de La Gloria to get a better view of the mountains that I'd glimpsed on my bus ride in:
Other than the wine tour and a hike up the Cerro de la Gloria, I didn't do much in Mendoza other than hang out in the plazas and the park and read a lot, but after my last couple of weeks in BA it was just what I needed. I spent a weekend in Mendoza and then took an overnight bus to Salta, which is in the far north of Argentina and where you start seeing the proximity to the Bolivian border, particularly in terms of the food and also in the elevation, it's over 1,000m up. The weather in Salta was even better than in Mendoza and I spent a lot of time just sitting in the sun at my hostel drinking beer and wine and playing cards. I also wandered around the local market and managed a trip up the cable car to get a view of the city, which was really nice and quite peaceful.
I was planning to spend quite a few days in Salta but Argentina turned out to be more expensive than I expected and I'd been hearing lots of talk about how cheap Bolivia was, so after just three days I decided on the spur of the moment to accompany a girl, Sophie, I met at the hostel on the overnight bus to La Quiaca on the border of Argentina and cross over into Villazon in Bolivia. We've been travelling in Bolivia together since then so it turned out to be a pretty good decision!
