I'm planning my trip to Patagonia for the next December - January.
I have some difficulty in planning the last leg, the one that would take me from El Chalten to Cochrane (Chile) to visit the nascent Patagonia National Park (http://www.conservacionpatagonica.com/).
I found an agency (www.chaltentravel.com/) that from El Chalten along the Ruta 40 reaching Perito Moreno, MAYBE (because they did not confirm) stopping at Los Antiguos. Here in theory there should be shuttle buses that bring in Chile Chico (Chile) and from here the buses going to Cochrane.
Has anyone ever walked this way and / or can give me information about transfer times and ease in finding the bus?
