In reply to Removed Usermartym:
i think there is meant to be good climbing in the cerro catedral range near bariloche; is across the border in argentina, but chile is so thin that you are never far from argentina at any point...
not sure about peru. a lot of the andes are rather crumbly volcanic stuff or shale, not great for cragging, but there must be some stuff
not sure i've been much help...
but sounds like a great trip, enjoy,
cheers
