7 days...S*$# lol
I'm afraid you are stuck around BsAs with only 7 days. for sure, go to colonia in Uruguay for a day. its really nice, I have a blog entry of photos if u want to check it outhttp://www.travelpod.com/travel-blog-entri...67354/tpod.html
that gives u 3 more days.
I feel u have 4 choices and u can only really choose one of them.
2. Fly to Bariloche, hike up volcano Tronador 3 -4 hrs There is a lovely Refugio near the top you can sleep in. you sleep between 2 glaciers and u get to see some of the best sun sets and sunrises. i stayed in a tent because it was free but. treated myself to some good Argentine wine(TAPIZ) and the girl working there made the most delicious stake. my friend shared his with me... I'm traveling on a budget... but the wine was so good i brought another bottle.
in the morning a local guide took us for a 3 hour climb on the glacier(one of the ones you sleep between, if you don't know how to climb he teaches you. It a quarter of the price to do this compared to other glaciers ion Patagonia and its less touristy. After the glacier expedition you can walk down the volcano and take a bus to bariloche. Also in bariloche(the town itself) it has the best ice cream eve! haha, oh and the chocolate isn't to bad. this option depends on the time of year your traveling. I have just spent 10 weeks hiking and climbing in Patagonia. and it is by far the most amazing place in south America i have been to so far. oh also Tronador is an amazing spot to see condors. I saw one 15 meters away.
here is a link to my bariloche entry, I spent 10 days there. The tronador option would be the most satisfying for sure.http://www.travelpod.com/travel-blog-entri...83073/tpod.html
3. Go to Mendoza, rent a bike and bicycle around the vineyards "taste testing"and get drunk...
4. The cowboy gaucho thing.
I personally didn't like El calafate.... it was to touristy for me. I have a link to an entry for that place, but I don't want to promote it... lol
id choose option 2 by the way... if you hadnt already guessed
peace, have fun. I know I AM!
