Hi all,
I'm sure these threads pop up from time to time but a search didn't give me any useful results. So here I am...

I've booked a trip to Argentina for March 2011. I'll be traveling solo at this point. I have 7 nights in Argentina.

What do I do? Where do I go?

Right now I'm planning on the first five nights in B.A. with a day trip to Uruguay. Then I'm thinking of taking a flight down to USH for 2 days to visit the southern part of the continent/country as well as do some hiking in the National Park. I can't find airfare less than US$540 right now. Is that normal?

Sure, I can read a tourist book but I have found people on FT have a ton of knowledge and are usually willing to share it so I'm open to any and all suggestions. BTW, I'm more of a culture, history and scenery type of tourist than I am into bars & clubs.

A few questions:
1. Are there any places to go hiking near B.A.? Or can I take a day trip from B.A. to somewhere for hiking?
2. What do you recommend I do in B.A. for five days? (I'll be reading through the BA Q&A thread as well).
3. Is USH the place to spend two days or should I consider elsewhere? I looked into Iguazu but my gut says to go south right now.

If it matters: I travel on a US passport and I enjoy photography.

Thanks in advance for your help.
