Quite a change of landscape! Patagonia is so reminiscent of parts of New Zealand, even the towns look quite similar.
Looking forward to see what photos you manage to capture at El Chalten and also at Perito Merino glacier (I assume you'll be headed there?). I've been to Torres Del Paine and around, which was stunning too, but regrettably didn't have enough time to make it to the Argentinian side. Makes me want to go back!
