I'm planning a short stay in the El Calafate area in late December. The idea is to see at least Perito Moreno Glaciar and the Magellanic Plover that I hope to see along Lago Argentino. I'm open to suggestions of other things to see/visit. El Chaltén is not on the agenda as we will already have been on a long trip by then, and I would most likely not do the steep uphill walk to get to see Fitz Roy.
