I`m going to stay in BA for abt 6 weeks (august and part of Sep). During that period I`d like to travel around region (the futher, the better). I`m going to travel mostly at weekends (maybe sometimes monday or friday as well). What I really care about, is the cost. The chaper, the better. As somebody from EU, cheap budget flight/bus means to me 50USD and 100 USD is for me normal price. (200USD is expensive). Of course, I don`t expect luxury for that prices. I don`t want to stay overnight, but if ticket will be chaper, that`s ok. My question is- where are the best places to go and what is the chapest way to travel? I`d like to ommit hick-hiking. I also already know about urugay. The most "visitworthy" destnations for me are Aconcangua, Santiago de Chile, Asuncion and Puerto Iguazu. Is there any way to pay less than 100USD to get there from BA? Maybe there are other locations, which are more worth seeing? I may travel alone, but maybe also with company of 1-3 ppl. I`m not fluent spanish speaker, I just know basics. Thanks for any advice.
