Photo Spot Details
El Chalten is famous for it’s renowned mountains, Cerro Torre and Fitz Roy. From photographers angle, I always recommend taking with you all the water-proof gear, e.g. raincoats and protection for your camera. Up in the mountains, in the base of Fitz Roy it is super-windy there and you can hardly stand, so I don’t think you can hold your tripod, which would be there an additional weight.
I’d recommend going there for 2-3 days and spend a night in El Chalten village (it’s costly though), so as you can start hiking early in the morning and catch glamorous morning light.
