I'm headed to Argentina on January first to climb Aconcagua and have given myself about 20 days to travel the country after the climb. Looking for any suggestions on places to go and see. I'll definitely be headed to Tierra del Fuego but would like to make some stops on the way down.

RUTA 40 by bus
This is a nice trip by bus from Bariloche to El Chalten

El Chalten is a paradise. You should stay one week there.
From El Chalten there is a bus to Calafate and there you can go by plane to Tierra del Fuego
Bye
