If you have time come by yacht - specialist charterers operate out of Ushuaia and the Falklands. If time is tight come on a cruise ship. There are around 40 visits a year between November and March. In winter the snow is down to sea level and cross-country skis, or snowshoes, are the way to get about. In summer you can walk normally, at least down near the coast.
