In reply to dctarrant2000:
There is a sport guidebook for the Bariloche area - available in the town. I have a copy, but I think it's currently in NZ where I am not... Also covers some areas just south of Bariloche (El Bolson and nearby). Lots of sport.
Might be worth checking out Piedra Parada, where the petzl Roctrip is currently. Some trad but also lots of sport.
There are a few fully bolted lines up at Frey and the area is definitely worth going to even if you don't have your rack - plenty of people just hike around there.
Some climbing in the area just south of Santiago - I can search out the names for you when I have more time.
