My partner and I are seeking some beta for Frey and El Chalten. Does anyone know what the occurrence is of ATMs where you can withdrawal cash in Bariloche and El Chalten? Also - does anybody have luck with a place to cache gear in either location? In Bariloche (Frey) it will be only for when we are out climbing (so perhaps for a week or so at a time). In Chalten we are looking to stash a duffel or two for about two months while we travel north.
There is an ATM in El Chalten. It can get cleaned out from time to time but is generally reliable. There are several hostels there that would likely let you leave a duffle for a nominal charge, especially if you had been a guest there.
