I am going to be in Argentina from March 26-May 10. I wanted to head to Bariloche and climb in Frey. I was thinking the last two weeks of April. I have checked average weather reports and know that it will be cold but maybe not that cold. If anyone has any advice that would be helpful please share it with me if you are willing. If you know of other places that are interesting to visit around the area that would be cool also.
