In the second half of December 2017, my wife and I went to Patagonia for a backpacking and hiking trip in Torres del Paine National Park and Los Glaciares National Park. We backpacked the Circuit trek in Torres Del Paine and we did day hikes to Laguna de los Tres (at the base of Mount Fitz Roy), Laguna Torre (at the base of Cerro Torre), and the Perito Moreno Glacier in Los Glaciares National Park. I wrote up a couple posts describing the treks in detail, which you can find below. I am happy to answer any questions here in the forum!
