I'm going to stay in Buenos Aires for little more than a week. I want to explore some of the nearby areas for a few days and not just stay in the city. There seem to be too many great options. I considered Sao Paolo, Santiago, Ushuaia or Medoza (for ruins). It seems like it might be fun to go on a ferry to Montevideo as well, but that sounds more like a day trip? I don't mind flying and specifically thought about going to Santiago to see the andes from above. I would love to see some ruins from the pre-european civilizatios, but I know I probably won't have time to make it to the most famous ones. I love unique and scenic places, urban or natural.
Please help!
