Hello everyone. Long time lurker/user here. I am planning on backpacking South America with a good friend of mine. We plan on leaving in early July, and returning late August or early September. A little background: We are both semi-fluent in Spanish, but we have no skills in Portugese. We're both 21 year old males from California. Very easy going, comical guys. We both study engineering at Cal Poly, and just want to go and have a good time and see the world. We'll be leaving from Los Angeles (LAX), and that's all we know as of right now. I'm pretty sure we'll be flying in to Rio de Janeiro, and stay in that area for about 6 days. Here's a list of what we'd like to see/go: Iguzu Falls Santiago, Chile Buenos Aires, Argentina La Paz Lima, Peru Cuzco, Peru Macchu Picchu (we will be hiking the trail) We don't know where to start initially, best methods to get around, other hot spots to see, what to bring, etc. I think we will fill in the gaps on getting around/what to see as we come closer to the date. I think we will be buying a one way ticket, and returning when we both decide to sometime in late August. I need advice on: What would be a good backpack? I won't bring my laptop, but maybe my iPhone, and definately a nice camera, as well as clothes/necessities. Money? Couch Surfing (if anyone knows what i'm talking about) Beaches Hostels Whatever you Mac Rumor people have to offer. Hopefully someone has advice. Thanks.
